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

<u>To find the surface area of the cuboid:</u>

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.
