Arusha draws a rectangular prism that is made up of two connected cubes,each with side length e.The surface area of a certain rectangular prism with edge length e is shown by the formula SA = 10e squared, and the volume of the prism is represented by the formula v = 2e cubed

What is the surface area of the prism if its edge length is 5 centimeter?

Arusha plans to build the prism and partially fill it with 150 cubic centimeters of sand. What fraction of the prisms volume will be filled by the sand?

Edge(e) = 5 cm

Surface area(10*e^2) = 10 * 5^2 = 250 squared centimeters

Volume of prism(2*e^3) = 2 * 5^3 = 250 cubic centimeters

Volume of sand = 150 cubic centimeters

Fraction of prism volume filled by sand = 150 / 250 = 3 / 5 = 0.6 (or 60% of cube volume)......(ANSWER)
