A rectangular storage container with an open top

is to have a volume of 13 m image . The length

of its base is twice the width. Material for the

base costs 14 per square meter. Material for the

sides costs 13 per square meter. Find the cost

of materials for the cheapest such container.

The illumination of an object by a light source

is directly proportional to the strength of the

source and inversely proportional to the square

of the distance from the source. If two light

sources, one three times as strong as the other,

are placed 14 ft apart, how far from the stronger

source should an object be placed on the line

between the sources so as to receive the least

illumination? Round the result to the nearest

hundredth.
