Mark has been collecting 11 map pencils each week for several weeks. he then gives 13 pencils to his friend. if p represents the number of weeks that mark has been collecting pencils, which expression represents the number of pencils mark has left?

answer:

side length of w = 45×w/1000t cm

step-by-step explanation:

the actual length of side t is .045 cm.

and we have to use the scale drawing to find the actual side with a length of w.

to get the scale we will use unitary method.

∵ length t is measured on scale=.045 cm

∴ length of w will be measured as (.045×w)/t cm

or length =

step-by-step explanation:

the formula of a volume of a cube:

a - length of edge

the formula of a surface area of a cube:

we have v = 729 ft³. substitute:
