see first of all we need to know the formulas . so the formulas are (only total surface area)
cuboid. 2(lb+bh+lh)
cube. 6a^2
cylinder. 2πr(h+r)
cone. πr(l+r)
where l=√h^2+r^2
sphere. 4πr^2
hemisphere. 3πr^2
frustum of cone. [πl(r+r')+πr^2+πr'^2]
hollow cylinder. 2π(R+r)(h+R-r)
Step-by-step explanation:
1. so. πr(l+r)
22/7×12/2(16+12/2)
22/7×6(22)
22/7×132
414.85 ft²
