Question

What is the surface area of a rectangular prism with sides: 5, 8 and 3

Answer 1

Surface Area of Rectangular Prism = 2 (wl + hl + hw)
                                                           = 2 [ (3 × 8) + (5 × 8) + (5 × 3) ]
                                                           = 2 (79)

Thus the Surface Area of Rectangular Prism with sides 5, 8, 3 = 158 units²
