The total volume of alloy in the post is about 900 cm³
What is a volume?
Volume is the amount of space occupied by a three dimensional shape or object.
Volume = length * width * height
The right rectangular prism measuring 9 cm by 9 cm by 28 cm. The alloy is 1.5 cm thick.
Length = 9 - 1.5 - 1.5 = 6 cm, width = 9 - 1.5 - 1.5 = 6 cm, height = 28 - 1.5 - 1.5 = 25 cm. Hence:
Volume = 6 * 6 * 25 = 900 cm³
The total volume of alloy in the post is about 900 cm³
