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: S.A = 67 [tex]units^{2}[/tex]
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 [tex]units^{2}[/tex]
