How do you calculate the volume of a rectangular prism?

Back

Volume = Length × Width × Height.

Front

What is the formula for the area of a triangle?

Back

Area of a triangle = 1/2 × Base × Height.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square meters (m²) or square centimeters (cm²).

Front

What units are used to measure volume?

Back

Volume is measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³).
