Answer» 1. Hollow Hemisphere Volume of hollow Hemisphere = 2π(R³ - r³)/3 Total surface area of a hemisphere: 2π(R² + r²) + π(R² - r²) = 3π(R² - r²) Curve surface area of a hemisphere: 2π(R² + r²) 2.Hollow sphere Volume of hollow sphere = 4π(R³ - r³)/3 Total surface area of hollow sphere = 4π(R² + r²) Curve surface area of hollow sphere = 4π(R² + r²) OUTER Curve surface area = 4πR² Inner Curve surface area = 4πr² 3.RIGHT CIRCULAR CONE Total surface area of hollow cone = πr(l + r) Curve surface area of hollow cone = πrl Base surface area = πr² 4. Hollow cuboid( same as Rectangular Prism) Total Surface Area of the Cuboid (or Rectangular Prism) = 2 x (lb + bh + hl) Volume of the Cuboid (or Rectangular Prism) = lbh. Curve surface area of Cuboid (or Rectangular Prism) = 2(l+ b) x h 5. Hollow cube Total Surface Area of the hollow cube = 6a² Curved Surface Area of the hollow cube = 4a² Volume of the hollow cube = a³ 6. Hollow cone Volume of hollow cone = 1/3πh((R² - r²) Curved Surface Area of the hollow cone = π(RL - rl) Volume of the hollow cone = V = π/3 x ( R² x H - r² x h ) Yes hollow cube and cuboid have same formula as solid cube and cuboid. The hollow cube is a cube with a cubical hole in the middle.The cube is the Platonic solid (also called the regular hexahedron). It is composed of six square faces that meet each other at right angles and has eight vertices and 12 edges. A cube with unit edge lengths is called a unit cube. This is a cuboid with a rectangular hole, two open, opposite sides and walls of equal thickness. The volume of a cuboid is calculated by multiplying the length by the width and the height of the cuboid. To calculated the volume of a cube, take the edge length of the cube to the power of 3. To determine the volume of a sphere, you have to take the diamater to the power of 3 and multiply it to π as well as 1/6.

Answer»

1. Hollow Hemisphere

Volume of hollow Hemisphere = 2π(R³ - r³)/3
Total surface area of a hemisphere: 2π(R² + r²) + π(R² - r²) = 3π(R² - r²)
Curve surface area of a hemisphere: 2π(R² + r²)

2.Hollow sphere

Volume of hollow sphere = 4π(R³ - r³)/3
Total surface area of hollow sphere = 4π(R² + r²)
Curve surface area of hollow sphere = 4π(R² + r²)
OUTER Curve surface area = 4πR²
Inner Curve surface area = 4πr²

3.RIGHT CIRCULAR CONE

Total surface area of hollow cone = πr(l + r)
Curve surface area of hollow cone = πrl
Base surface area = πr²

4. Hollow cuboid( same as Rectangular Prism)

Total Surface Area of the Cuboid (or Rectangular Prism) = 2 x (lb + bh + hl)
Volume of the Cuboid (or Rectangular Prism) = lbh.
Curve surface area of Cuboid (or Rectangular Prism) = 2(l+ b) x h

5. Hollow cube

Total Surface Area of the hollow cube = 6a²
Curved Surface Area of the hollow cube = 4a²
Volume of the hollow cube = a³

6. Hollow cone

Volume of hollow cone = 1/3πh((R² - r²)
Curved Surface Area of the hollow cone = π(RL - rl)
Volume of the hollow cone = V = π/3 x ( R² x H - r² x h )

Yes hollow cube and cuboid have same formula as solid cube and cuboid.

The hollow cube is a cube with a cubical hole in the middle.The cube is the Platonic solid (also called the regular hexahedron). It is composed of six square faces that meet each other at right angles and has eight vertices and 12 edges. A cube with unit edge lengths is called a unit cube.

This is a cuboid with a rectangular hole, two open, opposite sides and walls of equal thickness.

The volume of a cuboid is calculated by multiplying the length by the width and the height of the cuboid. To calculated the volume of a cube, take the edge length of the cube to the power of 3. To determine the volume of a sphere, you have to take the diamater to the power of 3 and multiply it to π as well as 1/6.
