${\tt{\red{\underline{\underline{\huge{Question}}}}}}$

The outer dimensions of a closed wooden box are 42cm×30cm×27cm. If the box is made of wood 1cm thick, determine the capacity of the box.

${\tt{\green{\underline{\underline{\huge{Answer}}}}}}$

Outer dimensions

l = 42 cm

b = 30 cm

h = 27 cm

Thickness of wood = 1 cm

Inner dimensions

l = 42 - (1 + 1) = 40 cm

b = 30 - (1 + 1) = 28 cm

h = 27 - (1 + 1) = 25 cm

∴Capacity of the box l × b × h

= 40 × 28 × 25

= 28000cm².

The capacity of the box is 28000cm². (Answer).
