The answer is h 142 your welcome
Answer:

Step-by-step explanation:
We are given the following in the question:
A storage shed is to be built in the shape of a (closed) box with a square base.
Volume = 150 cubic feet
Let s be the edge of square base and h be the height.
Volume of cuboid =

where l is the length, b is the base and h is the height.
Volume of box =

Area of base =

Cost of concrete for the base = $4
Cost of base($) = 
Area of roof =

Cost of material for the roof = $2
Cost of roof ($) = 
Area of 4 walls =

Cost of material for the side = $2.50
Cost of material of side($) =

Total cost
= Cost of base + Cost of 4 sides + Cost of roof

is the required cost function.
1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10
so it's 25m^2/10minutes
now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours)
25*12=300
answer is 300m^2
hope this helped
Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
