what is the volume of a cube with a side length of 7 inches?
a. 21 cubic inches
b. 343 cubic inches
c. 49 cubic inches
d. 294 cubic inches
check answer

Explanation:

Step1: Recall the volume formula for a cube

The volume \( V \) of a cube with side length \( s \) is given by the formula \( V = s^3 \).

Step2: Substitute the side length into the formula

Given that the side length \( s = 7 \) inches, we substitute this value into the formula: \( V = 7^3 \).

Step3: Calculate \( 7^3 \)

\( 7^3 = 7\times7\times7 = 49\times7 = 343 \).

Answer:

b. 343 cubic inches
