width = x
length = 2x+8
area = l x w
x<span>(2x+8)</span>=120

1.004 * 10^5
all scientific notation equations have to be a number greater than 1 but less than 10
then multiplied by 10 to the power of (move the decimal point to the right however many times you need, in this case 5) :)
56.5ft x 17ft x 1ft = 960.5ft^3.
The question wants the answer in ft^3. One of the measurements is given as 13 inches but that converts to 1ft. And with the volume formula for rectangles is widthxlenghtxheight. Plug in the numbers.
