Final answer:
The amount of space inside the toy box is w cubed times l cubed times h cubed.
Step-by-step explanation:
To find the total volume of the toy box, you multiply its width (w), length (l), and height (h). Representing each dimension with an exponent of 1, the expression w times l times h can be simplified to w cubed times l cubed times h cubed by adding the exponents, providing a concise way to express the total volume.
