Question

if V is the volume of a cuboid of dimensions a,b,c and S is its surface area,then prove that 1/V=2/S(1/a+1/b+1/c)

Answer 1

Answer:

Given dimensions of cuboid are a, b and c. Therefore, volume of cuboid, V = abc → (1) Surface area of cuboid, S = 2(ab + bc + ca) → (2) Now divide (2) with (1), we get
