Question

What is the volume of a shipping cube with dimensions of 3 1/2 feet

Answer 1

Answer:

$\large\boxed{V=42\dfrac{7}{8}\ ft^3}$

Step-by-step explanation:

The formula of a volume of a cube:

$V=a^3$

a - edge

We have

$a=3\dfrac{1}{2}\ ft$

Convert to the improper fraction:

$a=\dfrac{3\cdot2+1}{2}=\dfrac{7}{2}\ ft$

Substitute to the formula of a volume:

$V=\left(\dfrac{7}{2}\right)^3=\dfrac{7^3}{2^3}=\dfrac{343}{8}=42\dfrac{7}{8}\ ft^3$
