Find the surface area of a chalk box whose length, breadth and height are `16cm` `,8cm` and `6cm ` respectively.

Explanation

We have been given:
'length = `16 cm`, 'breadth = `8 cm`', 'height =` 6` cm
The total surface area of the box is:
'`2(lb + bh + hl) =2 ((16x8) + (8x6) + (16x6))`
`=2 (128 +48 +96)`
`=544 cm^2`.
