Question

A pastry chef is making a batch of mini petit fours

Answer 1

Remember that

The volume of a cube is equal to

`V=b^3`

where

b is the length side of a cube

In this problem

V=75 cm3

so

`75=b^3`

Solve for b

take the cubic root on both sides

`\begin{gathered} b=\sqrt[3]{75} \\ b=4.22cm \end{gathered}`

The answer is 4.22 cm
