1. You must apply the formula for calculate the volume of a rectangular prism and the formula for calculate the volume of a rectangular pyramid:
- Volume of the rectangular prism:
V1=lwh
Where l is the length, w i the width and h is the height
V1=(24 cm)(3 cm)(12 cm)
V1=864 cm^3
- Volume of the rectangular pyramid:
V2=lwh/3
Where l is the length, w is the width and h is the height
V2=(24 cm)(3 cm)(21 cm)/3
V2=504 cm^3
-The volume of the figure is:
Vt=V1+V2
Vt=1368 cm^3
The answer is: 1368 cm^3
