Question

The base of a square pyramid has a side length of 7 inches. The height of the pyramid is 19 inches.

What is the approximate volume of the pyramid?









A.

133 in3








B.

177 in3








C.

310 in3








D.

931 in3

Answer 1

V = a^2 * h/3

a = 7
h = 19

now sub
V = 7^2 * 19/3
V = 49 * 19/3
V = 931/3
V = 310.33....rounds to 310 in^3
