TRS b407. A teak wood log is cut first in the form of cuboid of length

1.	TRS b407. A teak wood log is cut first in the form of cuboid of length 2.3m, width 0.75m and ofthickness. Its volume is 1.104m3. How many rectangular planks of size 2.3mX0.75mx0.04mcut from the cuboid?(16)
Answer» As Volume = lbh ⇒1.104 = 2.30.7 h ⇒height, h = 1.104/1.61 = 0.6857 Now the cuboid is cut into cubes of size 2.3m0.75m0.04m, then Volume(V1) = 0.069m^3 Let the given cuboid is cut into n cuboids then volume of the given cuboid = n*vol of smaller cuboid n = V/V1 = 1.104/0.069 = 16

Answer»

As Volume = l*b*h

⇒1.104 = 2.3*0.7* h

⇒height, h = 1.104/1.61 = 0.6857

Now the cuboid is cut into cubes of size 2.3m*0.75m*0.04m, then Volume(V1) = 0.069m^3

Let the given cuboid is cut into n cuboids then volume of the given cuboid = n*vol of smaller cuboid

n = V/V1 = 1.104/0.069 = 16
