volume of a cuboid of length = \(x\); breadth = \(y\); and height = \(z\) is given by \(x * y * z\)
we are asked to calculate volume on both of the two quantities so let us have

Qty A as \((x+10) * Y * Z\) and Qty B as \(X * Y * (Z+10)\)

Notice that the measure of the sides are positive hence cancelling Y from both quantities will not affect our comparison and keep the syntax of the equation intact.


Now,

Qty A = \((x+10) * Z\)
Qty B = \(x* (z+10)\)

At this point chose any value for \(X\) and \(Z\) such that \(Z>x\) and both \(X\) and \(Z\) are +ve

For eg. \(x =1\) and \(Z = 2\)

Qty A = \((1+10) * 2 = 22\)
Qty B = \(1 * (2+10) = 12\)

Qty A is bigger
