Find the lateral area $L$ of a pyramid if slant height $s = 6.1 cm$ and base area $B = 40.96 cm$ .

Answer

$78.08 cm$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

After substituting $B = 40.96 cm$ we have:

B = a^{2}

a^{2} = 40.96 cm

a = 40.96 cm

a = 6.4

STEP 2: find lateral surface $L$

To find lateral surface $L$ use formula:

L = 2 \cdot a \cdot s

After substituting $a = 6.4 cm^{0}$ and $s = 6.1 cm$ we have:

L = 12.8 \cdot 6.1 cm

L = 78.08 cm
