Question

Find the surface area of the right rectangular prism shown below.

Answer 1

Answer:

Step-by-step explanation:

Surface area=2*(lb+lh+bh)

=2*( 5*4 + 5*1.5 + 4*1.5)

=2* ( 20 + 7.5 + 6.0)

= 2 * 33.50

= 67.0 = 67 square units

Answer 2

Answer: S.A = 67 $units^{2}$

Step-by-step explanation:

The formula for calculating the  surface area of right rectangular prism is given by :

Surface area = 2 (wl + hl + hw )

w = 5

l = 4

h = 1.5

wl = 5x4 = 20

hl = 1.5 x 4 = 6

hw = 5 x 1. 5 = 7.5

substituting into the formula

Surface area = 2 (20 + 6 + 7.5)

S.A = 2 ( 33.5)

S.A = 67 $units^{2}$
