Find the area $ A $ of a pyramid if side $a = 0.6$ and slant height $s = 0.8$.

$A = 1.32$

STEP 1: find base area $ B $

To find base area $ B $ use formula:

$$ B = a^2 $$

After substituting $ a = 0.6 $ we have:

$$ B = 0.6^2 $$ $$ B = 0.36 $$

STEP 2: find lateral surface $ L $

To find lateral surface $ L $ use formula:

$$ L = 2 \cdot a \cdot s $$

After substituting $ a = 0.6 $ and $ s = 0.8 $ we have:

$$ L = 1.2 \cdot 0.8 $$$$ L = 0.96 $$

STEP 3: find total surface $ A $

To find total surface $ A $ use formula:

$$ A = B + L $$

After substituting $ B = 0.36 $ and $ L = 0.96 $ we have:

$$ A = 0.36 + 0.96 $$ $$ A = 0.36 + 0.96 $$ $$ A = 1.32 $$
