Answer:
The shower uses less water
Step-by-step explanation:
In 12min the shower will use:
Shower = 1.75 gallons/min * 12min = <em>21</em> gallons of water
The bathtub at full capacity will store approximately:
Full Bathtub = 5*4*3 = 60ft^3 * 7.5 gallons/ft^3 = 450 gallons of water.
Since the tub is half-full, it will use:
Half Bathtub = <em>225 </em>gallons of water. A lot more than the shower.
The hexagon is made up of 6 triangles. So we need to multiply the area of the triangle by 6 to find the answer.
Area of triangle = b x h / 2
A = 14 x 12.1 / 2
A = 169.4 /2
A = 84.7 ft squared
Area of hexagon = 84.7 x 6
= 508.2 ft squared
