Question

the formula of volume and surface area

Answer 1

surface area of sphere =4×pie×r^2
and volume of sphere =4/3×pie×r^2

hope this helps :-)

Answer 2

volume of cube is a^3 and cuboid is l*b*h, total surface area of cube is √6a^2 and cuboid is 2(lb+bh+lh) lateral surface area of cube is 4a^2 and cuboid is 2(l+b)*h volume of sphere is πr^2h ,TSA is 2πrh and LSA is 2πr ( h+r)
