The surface area of rectangular prism is 360 square inches
Solution:
Given that rectangular prism of the length is 18 cm the width 6 cm and the height 3 cm
To find: Surface area of rectangular prism
The Surface area of rectangular prism is given by formula:
[tex]A=2(wl+hl+hw)[/tex]
Where,
"l" is the length and "h" is the height and "w" is the width of prism
From given,
l = 18 cm
w = 6 cm
h = 3 cm
Substituting the values in formula,
[tex]A = 2((6 \times 18) + (3 \times 18) + (3 \times 6))\\\\A = 2(108+54+18)\\\\A = 2 \times 180\\\\A = 360[/tex]
Thus surface area of rectangular prism is 360 square inches
