what is the surface area of a rectangular prism l= 5.5cm, w=4.5cm, h=3.5cm

Question

lenght=5.5, wide=4.5, hight=3.5.

Answer 1

Surface area of rectangular prism is 2(lb+bh+lh)

l = 5.5cm, b = 4.5cm, h = 3.5cm.

= 2[5.5(4.5)+4.5(3.5)+5.5(3.5)]

= 2[24.75+15.75+19.25]

= 2(59.75)

= 119.5

Surface area  of given rectangular prism is 119.5cm^2.
