Question

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

Answer 1

Answer:

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

Step-by-step 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,

$S = 2[(8\times 13 )+ (13 \times7) + (7\times 8)]$

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

$S = 2(251)$

$S = 502 mm^2$
