The video tutorial explains how to calculate the volume of a rectangular prism using unit cubes. It begins by introducing the concept of volume with a cube of side 1 cm, defining it as a cubic centimeter. The tutorial then describes a rectangular prism with dimensions 4 cm by 3 cm by 2 cm and demonstrates how to fill it with unit cubes. The process involves calculating the number of cubes in each layer and multiplying by the number of layers to find the total volume. The final volume is calculated as 24 cubic centimeters, reinforcing the formula for volume calculation: length times width times height.

What is the unit of volume when using a cube with a side length of 1 cm?

• Meter

• Liter

• Cubic centimeter

• Square centimeter

If a rectangular prism has dimensions of 4 cm by 3 cm by 2 cm, how many unit cubes with a side length of 1 cm are needed to fill it?

• 24 cubes

• 12 cubes

• 18 cubes

• 30 cubes

How many layers of unit cubes are there in a rectangular prism with a height of 2 cm?

• 2 layers

• 4 layers

• 1 layer

• 3 layers

What is the formula to calculate the volume of a rectangular prism?

• Length + Width + Height

• Length × Width

• Length × Width × Height

• Width × Height

If the volume of a rectangular prism is 24 cubic centimeters, which of the following could be its dimensions?

• 3 cm × 3 cm × 3 cm

• 2 cm × 2 cm × 6 cm

• 2 cm × 3 cm × 4 cm

• 4 cm × 4 cm × 1 cm
