Question

Find the surface area of this cubiod

Answer 1

Total surface area = 62 cm^2.

Explanation:

There are 2 faces each of area 2 * 3 = 6, = 12 cm^2.

There are 2 faces each of area 10, = 20 cm^2.

There are 2 faces each of area 15, = 30 cm^2.

12 + 20 + 30 = 62 cm^2.

Answer 2

surface area is 2(lb + bh + lh)

I think this is the right formula
