Q. What is the volume of a square-based pyramid with base side length of 8 inches and a height of 12 inches? Write your answer in the box provided.□
Identify formula: Identify the formula for the volume of a square-based pyramid.The formula for the volume of a square-based pyramid is V=31×base area×height.Here, the base is a square with side length s, so the base area is s2.
Calculate base area: Calculate the base area of the pyramid.The side length of the base is 8 inches, so the base area is 8 inches ×8 inches =64 square inches.
Substitute into formula: Substitute the base area and the height into the volume formula.Using the base area of 64 square inches and the height of 12 inches, the volume V is calculated as follows:V=(31)×64 square inches×12 inches.
Perform multiplication: Perform the multiplication to find the volume.V=31×64×12V=31×768V=256 cubic inches.
