Question

Which best compares the volumes of pyramid X and pyramid Y?

Two pyramids X and Y kept apart a distance of 10cm from the its center points. The pyramid X has a square base with base length of 5 cm, base width of 6cm and makes a 90 degree angle with the pyramid height. A pyramid Y has a triangular base with 2 sides measuring 7.5 cm and 8 cm respectively.

A. The volumes of X and Y are equivalent.
B. The volume of X is half the volume of Y.
C. The volume of Y is half the volume of X.
D. The volume of X is 10 times the volume of Y.

Answer 1

A. The volumes of X and Y are equivalent.

Explanation:

FORMULA: 1/3Bh

X:

First find the base area: B= (5)(6)

= 30

Substitute the values for B and h in the formula of the volume of a pyramid.

V= 1/3 Bh

=1/3 (30)(10)

V=100

Y:

Use the triangle Formula to find the base: 1/2 (7.5)(8)= 30

Use the Volume Formula for the Pyramid: 1/3 (30)(10)

V= 100
