Jack wants to fill a rectangular box with sand. the length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. each bag of sand contains 0.15 cubic foot of sand. how many bags of sand will jack need to fill the box completely? [1 foot = 12 inches] numerical answers expected!

The number of bags of sand that Jack need to fill the box completely are:

                                        2

The length(l) of the sand box is 3 feet, width(w) is 6 inches, and height(h) is 2.4 inches.

Also,

1 foot=12 inches

This means that:

1 inch=1/12 foot

i.e.

6 inches=0.5 feet

i.e.

w=0.5 feet

and

h=2.4 inches

i.e.  h=0.2 feet

Now, we find the volume of the rectangular box.

The volume of the rectangular box is given by:

Volume=lwh

Hence,

Volume=3×0.5×0.2

i.e.

Volume=0.3 cubic feet.

Also, the volume of one bag of sand= 0.15 cubic feet

This means that the number of bags of sand that will fill the box completely is:

(Volume of rectangular box) / (Volume of one bag of sand)

=   0.3/0.15

=2

Hence, number of bags =2
