Achild's tent can be modeled as a pyramid with a square base whose sides measure 60 inches and whose height measures 84 inches. what is the volume of the tent, to the nearest cubic foot?

The volume of the tent is

Step-by-step explanation:

we know that

The volume of the square pyramid (child's tent) is equal to

we have

substitute

58 cubic feet

Step-by-step explanation:

Given: The sides of the square base of the pyramid (s)= 60 inches

In foot , the sides of the square base of the pyramid (s)=

The height of the pyramid = 84 inches

In feet, height of the pyramid =

We know that the volume of a square pyramid is given by ;-

Hence, the volume of the tent =58 cubic feet

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
