Question

Calculate the volume of the composite solid . 2 cm 3 cm 2 cm 4 cm 3 cm 4 cm 8 cm

Answer 1

Notice that the solid consists of an 8x4x4cm rectangular prism minus a 3x4x2cm rectangular prism (the gap shown in the image).

Therefore, the volume of the solid is

`V_(solid)=(8*4*4)-(3*4*2)=128-24=104`

The answer is 104cm^3
