Question

Find the surface area of the prism 8mm 13mm 7mm

Answer 1

The surface area of the prism is
`S = 502 mm^2`

Explanation:

Given:

Length of the prism = 8mm

Width of the prism = 13mm

Height of the prism = 7mm

To Find:

The surface area of the prism = ?

Solution:

Surface area of a prism is given by

S =2 ( lw + wh + hl )

Substituting the values we get,

`S = 2[(8* 13 )+ (13 *7) + (7* 8)]`

`S = 2[(104 )+ (91) + (56)]`

`S = 2(251)`

`S = 502 mm^2`
