evaluate the volume and surface area of a

Question

Evaluate the volume and surface area of a rectangular solid:

Calculate the volume & surface area of a rectangular solid along with a =   3", b = 4", & c = 5". 

Solution:

V = (a)(b)(c)                            SA  = 2(ab + ac + bc)

V = (3)(4)(5)                           SA  = 2[(3)(4) + (3)(5) + (4)(5)]

V = (12)(5)                              SA  = 2[12 + 15 + 20]

V = 60 cubic inches                SA = 2[47]

SA = 94 square inches
