Question

7. Find the volume of wood required to make a top
open box of dimensions 15 cm by 12 cm by 8 cm
and the thickness of the wood is 1 cm.​

Answer 1

Answer:

Step-by-step explanation:

The outer volume is 17.5 x 14 x 10 cm^3 = 2450 cm^3  

Assuming it is open on the top, the open space is (length - 2 * thickness) * (width - 2 * thickness) * ( height - thickness)  

Notice 7.5 mm = 0.75 cm and 2 x 7.5 mm = 1.5 cm  

Open space = (17.5 - 1.5 ) ( 14 - 1.5 ) (10 - 0.75) = 16 * 12.5 * 9.25 = 1850 cm^3  

The volume of wood is 2450 - 1850 = 600 cm^3
