How to calculate the area of a rectangular prism?
To calculate the area of a rectangular prism we must use the following formula:
- V = area of the base of the prism × height of the prism
We can use this formula to solve several of the problems posed as shown below:
problem E
Volume = (15cm × 15cm) × 15cm
Volume = 225 × 15cm
Volume = 3,375 cm³
Problem H
Volume = (15cm × 18cm) × 12cm
Volume = 270 × 12cm
Volume = 3,240 cm³
Problem P
Volume = (7cm × 7cm) × 7cm
Volume = 49 × 7cm
Volume = 343 cm³
Problem R
Volume = (9cm × 12cm) × 8cm
Volume = 108 × 8cm
Volume = 864 cm³
