Malloree wants to calculate the cost of keeping her hot tub heated to a constant temperature. Her hot tub is a square 7 feet on a side, and it is 2.75 feet deep. If it costs $0.03 to heat one gallon of water per month, what would it cost her to keep her tub heated for one month? (1 cubic foot = 7.5 gallons)

    It's a square so it means you have to multiply 7*7*2.75 to get 134.75

    Multiply that by 7.5 because one cubic foot holds 7.5 gallons

    1010.625 *.03 since its 3 cents per gallon

    30.318

    Round up

    $30.32 is the answer

    Step-by-step explanation:

    Mallorie's hot tub is a square. The formula for determining the volume of the square hot tub is expressed as

    Volume = L * W * H

    Where

    L and W represents the length of each side of the hot tub.

    H represents the depth of the hot tub.

    Her hot tub is a square 7 feet on a side, and it is 2.75 feet deep. Therefore,

    Volume = 7 * 7 * 2.75 = 134.75ft^3

    We would convert 134.75ft^3 to gallons. It becomes

    134.75 * 7.5 = 1010.625 gallons

    If it costs $0.03 to heat one gallon of water per month,

    then the amount it will cost her to keep her tub heated for one month would be

    1010.625 * 0.03 = $30.32
