surface area = 2(wl +hl+hw)
w=3
l=8
h=5
wl=3*8 =24
hl=5*8 =40
hw=5*3 =15
24+40+15 = 79
2*79 = 158 feet^2
The surface area of the rectangular prism is 158 square feet.
The surface area of any given object is the area or region occupied by the surface of the object.
Surface Area = 2{(h × l) + (h × w) +(l × w)]
Where,
l is the length of the rectangular prism
h is the height of the rectangular prism
w is the width of the rectangular prism
According to the given question
Length of the rectangular prism = 8 feet
width of the rectangular prism = 3feet
height of the rectangular prism = 5 feet.
Therefore,
the surface area of the rectangular prism = 2[(8 × 5)+ ( 5 × 3) + ( 8 × 3)]
surface area of rectangular prism = 2[ 40 +15 +24} = 158 square feet.
Hence, the surface area of the rectangular prism is 158 square feet.
