To find the square footage of a cube, simply times the length by width by height.
For example: 2 x 3 x 4 = 24cubic feet (24ft3).
I'm not sure where the 5 feet comes from in your question?
Apparently there is a mathematical object known as a hypercube.
So 2 x 3 x 4 x 5 = 120!
10*5 = 50 sq ft
245 ft3
1 meter = 3.281 feet -so- 4 meters = 13.124 feet 5 meters = 16.405 feet -thus- 13.124 ft X 16.405 ft = 215.29922 sq. ft. Answer: 4 meters X 5 meters = 215.29922 sq. ft.
x5 is an expression: there can be no answer to it.
Convert everything to feet, then multiply length x width x height. Answer is in cubic feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 15 square feet.
There are: 0.5*8*5 = 20 square feet
25 Ft2
Abswer = 88 x 5 = 440 sq feet
10*5 = 50 sq ft
26 square feet? That is not a roof that is a patch. 5' X5' is 25 square feet, so a minimun job call for a roofer, about $100
100. here's the math: (4x5)x5 (20)x5 =100
6 x5 = 30 SQUARE feet. If you want cubic feet you will have to measure how thick the bed is, and add that dimension into your calculation.
This can either be written as x5.5, or x5 times square root of x. √x11 = √x10x = x5√x
x5 square units.
245 ft3
That is 420 cubic ft.
