1.	If V is the volume of a cuboid of dimensions x, y, z and A is its surface area, then AV(a) x2y2z2(b) 121xy+1yz+1zx(c) 1x+1y+1z(d) 1xyz
Answer» If V is the volume of a cuboid of dimensions x, y, z and A is its surface area, then $\frac{A}{V}$ (a) x²y²z² (b) $\frac{1}{2} (\frac{1}{x y} + \frac{1}{y z} + \frac{1}{z x})$ (c) $(\frac{1}{x} + \frac{1}{y} + \frac{1}{z})$ (d) $\frac{1}{x y z}$
