Question

A right rectangular prism has base dimensions of 3 inches by 12 inches and a height of 5 inches. An oblique rectangular prism has base dimensions of 4 inches by 9 inches and a height of 5 inches.Is it possible to have all the volumes would be the same?

A. Yes, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.
B. Yes, because the figures are congruent.
C. No, because the cross-sectional areas are not the same.
D. No, because only the bases have the same area, not every cross section at every level parallel to the bases.

Answer 1

Answer with explanation:

Right Rectangular prism 1

Dimension of Base =3 inches by 12 inches

Height =5 inches

→Volume of Right Rectangular prism 1

= Area of Base × Height

= 3 × 12 ×5

= 180 cubic inches

Right Rectangular prism 2

Dimension of Base =4 inches by 9 inches

Height =5 inches

→Volume of Right Rectangular prism 2

= Area of Base × Height

= 4 × 9 ×5

= 180 cubic inches

Option A: Yes, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.

Answer 2

The volumes will be the same, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.
