Question

find the volume of the prism.
a. 232 ft³
b. 343 ft³
c. 240 ft³
d. 251 ft³

Explanation:

Step1: Identify the prism type

The given prism is a cube with side - length \(a = 7\) ft.

Step2: Recall the volume formula for a cube

The volume formula of a cube is \(V=a^{3}\).

Step3: Substitute the value of \(a\) into the formula

Substitute \(a = 7\) ft into \(V=a^{3}\), we get \(V = 7^{3}=7\times7\times7=343\) \(ft^{3}\).

Answer:

B. 343 \(ft^{3}\)
