Problema Solution
: You have to purchase rubber chips to fill your playground so that no one gets hurt. One bag covers 2m cuped
. The chips need to be at least 5cm deep. How many bags will you
need?
the playground is 999m squared
please can you discribe for me step by step
Answer provided by our tutors
1 bag = 2 m^3
h = 5 cm = 5/100 m = 1/20 m the depth of the playground
A = 999 m^2 the area of the playground
the total volume of the chips needed for the playground is
V = A*h
V = 999*(1/20)
V = 49.95 m^3
let n = the number of bags needed, n is integer and we know that 1 bag = 2 m^3
the volume of n bags is: 2*n
the volume of n bags needs to be at least equal to V that is we have
2*n => 49.95 divide both sides by 2
n => 49.95/2
n => 24.975
since n needs to be in integer we have n = 25
25 bags will be needed.
