Arectangular prism has dimensions of 2x, 3x, and 5x. write an expression for the total surface area of the prism.

A = 62x^2

Step-by-step explanation:

This rect. prism has 6 faces, stemming from two each of the areas of the top, the end and the side of the prism.

top surface area:  (2x)(3x) = 6x^2

end surface area:  (2x)(5x) = 10x^2

side surface area:  (3x)(5x) = 15x^2

Total surface area:  A = 2(6x^2 + 10x^2 + 15x^2)

or:  A = 2(31x^2) = 62x^2
