A rectangular prism and cube have equal volumes. The length of the rectangular prism is 12cm and its width is 8cm. If each side of the cube is 12cm, then what is the height of the rectangular prism in centimeters?□
Q. A rectangular prism and cube have equal volumes. The length of the rectangular prism is 12cm and its width is 8cm. If each side of the cube is 12cm, then what is the height of the rectangular prism in centimeters?□
Identify Volume of Cube: Identify the volume of the cube.Since the length of each side of the cube is 12cm, the volume of the cube (Vcube) can be calculated using the formula for the volume of a cube, which is side3.Vcube=12cm×12cm×12cmVcube=1728cubic centimeters
Express Volume of Prism: Express the volume of the rectangular prism.The volume of the rectangular prism Vprism is equal to the volume of the cube since they have equal volumes.Vprism=VcubeVprism=1728 cubic centimeters
Calculate Height of Prism: Calculate the height of the rectangular prism.The volume of a rectangular prism is calculated by multiplying its length, width, and height. We have the volume and the dimensions for length and width, so we can solve for the height h.Vprism=length×width×height1728cm3=12cm×8cm×h
Solve for Height: Solve for the height.To find the height, divide both sides of the equation by the product of the length and width.h=(12cm×8cm)1728cm3h=96cm21728cm3h=18cm
