<h3>What is Volume?</h3>
Surface area is the amount of space covering the outside of a three-dimensional shape.
Surface Area of Cone,
= πrl + πr²
=3.14*8*15.77 + 3.14* 8*8
= 597.61804 mm²
Surface Area of triangular pyramid,
= apothem * slant height * length
= 73.6 m²
Surface Area pentagonal pyramid
= B + LA
= 247.75 + 5 ( 1/2*12*19.5)
= 247.75 + 5 ( 117)
= 832.75 in²
Surface area of square pyramid
= P*l /2
= 2400 ft²
