The base of a cuboid is a square of sides 8 cm. The height of the cuboid is 5 cm. What is the volume of the cuboid?

To calculate the volume of a cuboid (which is a rectangular prism), you can use the formula:

Volume = length × width × height

Since the base of the cuboid is a square, the length and the width are the same, which are both given as 8 cm. The height of the cuboid is given as 5 cm.

Using these dimensions:

Volume = 8 cm × 8 cm × 5 cm
Volume = 64 cm² × 5 cm
Volume = 320 cm³

So, the volume of the cuboid is 320 cubic centimeters.
