GIVEN -
- Water tank which is in a shape of right rectangular prism
Dimensions = 6 feet × 4 feet × 7 feet
TO FIND -
SOLUTION -
Using formula of surface area of right rectangular prism -
Surface area =
[tex]2(wl + hl + hw)[/tex]
L = length
w = width
h = height
( assumimg 6 feet = L , 4 feet = W , 7 feet = h)
Putting value of L, W and H in the equation. we get,
=2(4 × 6 + 7 × 6 + 7× 4)
= 2(24 + 42 + 28)
= 2( 94)
= 2 × 94
= 188
