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

<em>a</em> - 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

2a=bh
Then divide both sides by b.
2a/b=h
