Question

Surface area of solid cuboid 8cm 6cm 2cm

Answer 1

152
`\text{cm}^2`

Explanation:

We know that the total surface area of a cuboid is the sum of the surface area of all six of its faces.

We also know that each opposing side has the same surface area. Thus the total surface area is equal to:

`2*(8*6+8*2+6*2)\\\\=2*(48+16+12)\\=2*76\\=152`(
`\text{cm}^2`)
