Pleasee help what’s the lateral surface area please help

Lateral surface area of the cuboid = 84 square inch

Total surface area = 119.28 square inch

Step-by-step explanation:

Lateral surface of the cuboid = Total surface area of the cuboid - Area of the top and base of the cuboid

Total surface area = 2(lb + bh + hl) - 2(lb)

Here, l = length of the cuboid

b = width of the cuboid

h = height of the cuboid

Therefore, Lateral surface area of the given cuboid = 2(bh + hl)

= 2(2.1 × 4) + 2(4 × 8.4)

= 16.8 + 67.2

= 84 square inch

Total surface area of the cuboid = 2(8.4×2.1 + 2.1×4 + 4×8.4)

= 2(17.64 + 8.4 + 33.6)

= 2(59.64)

= 119.28 square inch

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
