Answer:

Approximately 38 cube inches of wax.

Explanation:

The candle can be assumed to have the shape of a cylinder, so that;

volume of a cylinder =
$\pi$
r^(2) h

where: r is the radius and h the height of the cylinder.

Thus,

volume of each candle =
$\pi$
r^(2) h

But radius is 1 inch and height is 4 inches, then;

volume of each candle =
(22)/(7) x
1^(2) x 4

=
(22)/(7) x 1 x 4

= 12.5714

volume of each candle = 12.6 cube inches.

Therefore, for the three candles;

volume of the three candles = 3 x 12.5714

= 37.7142

volume of the three candles = 37.7142 cube inches

The amount of wax required for the three candles is approximately 38 cube inches.
