PLEASE HELP ME Calculate the surface area of a prism with the following dimensions.
The length (1) = 7 units, the width (w) = 2 units and the height (h) = 6 units:
278 sq. units
136 sq. units
176 sq. units
587 sq. units

Please select the best answer from the choices provides

136 units squared

Step-by-step explanation:

I will assume this is a rectangular prism since it isn't specified.

The surface area of a rectangular prism: SA = 2(lw+lh+wh).

Plugging in your dimensions: SA = 2(7*2 + 7*6 + 2*6) = 2(14+42+12) = 2(68) = 136 units squared.

answer4 to the second power is 16

and 4 to the third power is 64,

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
