Answer: S.A = 67
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
Solve:
We need to isolate k, so multiply both sides by the denominator, which is 64. When we do that, the fraction will cancel and we get:
If you want to check, plug in your answer to the original equation and see if it is true:
This statement is true, so .
