Case Study
Cuboidal shapes are considered best in the category of rigid
packaging as it is
most suited across the packaging supply
chain both for performance & cost.
So Devnand decided to pack his products in a
cuboidal box of breadth x centimetres, length
3 cm longer than the breadth and height 4 cm
shorter than length
The volume and surface area of the cuboidal
box is expressed as a polynomial in x.
If the volume is represented by the polynomial
V(x) = x + 2x2 - 3x
What would be the volume if breadth of the cuboid is 4 cm?

When breadth is 5, surface area of the box is 16 cm2 and the surface area is
represented by the equation 3x2 - ax - 4. Find the values of “a” [1 mark]
