Answer:
Explanation:
Given dimensions of the rectangular prism ,
4"×3"×7"
We know, Total surface area of a cuboid= 2(lb+bh+hl)
where, l=length of the cuboid
b= breadth " " "
h= height " " "
Since, a rectangular prism holds the shape of a cuboid, therefore it's surface area should also be 2(lb+bh+hl)
Now, surface area of the rectangular prism = 2(4×3+3×7+7×4)
=2(12+21+28)
=2×61
=122 square inches.
