|
Answer» In order for any three given LENGTHS to be the SIDES of a right angled triangle , they have to be a pythogarean triplet. pythogoras triplet is given by , 2m , m²+1 , m²-1 2m is the least value in the triplet and m²+1 the greatest. If we substitute the values, 2m = 8 m = 4 m²+1 = 16+1 =17 m²-1 = 16 - 1 = 15 this proves that they are the sides of a right angled triangle. hope it helped and pleeease mark as BRAINLIEST:) |

two cubes with area 64 cm^3 each are joined end to end what is the surface area of the resulting cuboid? |
|
Answer» Step-by-step explanation: The question is not very clear If you mean that the VOLUME of the cube is 64 cm³ then Volume of a cube = a³ Where a = SIDE of the cube => a³ = 64 => a = ∛64 => a = 4 cm Now the dimensions of the resulting cuboid formed by joining the ENDS of the cubes are Length = 4+4 = 8 cm Breadth = 4 cm Height = 4 cm Surface area of the cuboid = 2 * [ (l*b) + (b*h) + (l*h) ] Where l, b, and h, are the length, breadth, and height of the cuboid respectively Substhe values and solving, we get Surface area = 2*[ (4*8) + (4*4) + (8*4) ] = 2 * [ 32 + 32 + 16 ] = 2 * 80 = 160 cm² Therefore, the surface area = 160 cm² Now, if you mean the surface area of the cube = 64 cm², then Surface area of a cube = 6 * a² Where a = side of the cube => 6 * a² = 64 => a² = 64/6 => a = √(64/6) = 8/√6 = 8/2.4 = 10/3 = 3.3 cm Now, by joining the cubes together, the new dimensions are Length = 3.3 + 3.3 = 6.6 Breadth = 3.3 Height = 3.3 The surface area of the cuboid = 2 * [ (3.3*6.6) + (3.3*3.3) + (6.6*3.3) ] = 2 * [ 21.78 + 21.78 + 10.89] = 2 * 54.45 = 108.9 cm² Therefore, the surface area = 108.9 cm² Please brainlist my answer, if helpful! |
