A rectangular prism has dimensions 5 by 6 by x. If the total surface area of the prism is 157.9 square units, what is the value of x?

What is the volume of the above prism?

asked by carlos
  1. Surface Area = 2wL +2LH + 2Hw
    and you have a length of 5, a width of 6, so your height is X
    157.9 = (2)(6)(5) + 2(5)(x) + 2(x)(6)
    Simplify, gather like terms and solve for x

    then to find the volume sub your values into Volume = LWH
