Mensuration Practice Test 10

Let x = 2, y = 3 and z = 4 where x < y < z volume
2 × 3 × 4 = 24 $\mathit{c}{\mathit{m}}^3$
Case I when x is increased by 1
3 × 3 × 4 = 36 $\mathit{c}{\mathit{m}}^3$
Case II when y is increased by 1
2 × 4 × 4 = 32 $\mathit{c}{\mathit{m}}^3$
Case III when z is increased by 1
2 × 3 × 5 = 30 $\mathit{c}{\mathit{m}}^3$
Volume is greatest when x is increased.
