Question

Find the volume of each of the following cubes. a. s = 7 kilometers b. s = 11 yards

Answer 1

Answer:

a) 343 kilometres³

b) 1331 yards³

Step-by-step explanation:

The volume of a cube is calculated using the following formula, where S is the side length of the cube:

$V=S^{3}$

a) Cube with side length, s = 7 kilometres

$V_{a}=7^{3} \\V_{a}=343$

a) Cube with side length, s = 11 yards

$V_{a}=11^{3} \\V_{a}=1331$

Answer 2

Answer:

Part 1) $V=343\ km^{3}$

Part 2) $V=1,331\ yd^{3}$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=s^{3}$

where

s is the length of the cube

Part 1)

we have

$s=7\ km$

substitute in the formula

$V=7^{3}$

$V=343\ km^{3}$

Part 2)

we have

$s=11\ yd$

substitute in the formula

$V=11^{3}$

$V=1,331\ yd^{3}$
