The surface area of the cuboid is 276 in².
Solution:
Given data:
Length of the cuboid = 10 in
Width of the cuboid = 4 in
Height of the cuboid = 7 in
To find the surface area of the cuboid:
Surface area of the cuboid = 2(lw + wh + lh)
= 2(10 × 4 + 4 × 7 + 10 × 7)
= 2(40 + 28 + 70)
= 2(138)
= 276 in²
The surface area of the cuboid is 276 in².
