What is the value of n3 equals 8000?
N^3=8000 Take the cube root of N, and do it to the 8000 N=20 Because 20x20x20=8000
How do you simplify 20 to the third power?
a to the b power means b lots of a, all multiplied together. Thus, 203 or "20 to the 3rd power" can be rewritten as 20x20x20. If this value is calculated it comes out as 8,000. Thus 20 to the 3rd power can be simply expressed as 8,000.
Cube numbers up to 30?
1x1x1=1 2x2x2=8 3x3x3=27 4x4x4=64 5x5x5=125 6x6x6=216 7x7x7=343 8x8x8=512 9x9x9=729 10x10x10=1000 11x11x11=1331 12x12x12=1728 13x13x13=2197 14x14x14=2744 15x15x15=3375 16x16x16=4096 17x17x17=4913 18x18x18=5832 19x19x19=6859 20x20x20=8000 21x21x21=9261 use calculator to work out the rest cant be bothered to write out any more LOL :-)
How many 20x20x20 inch boxes does it take to cover 400 square feet?
Depends on the shape of the 400 square foot area, and how you are using the boxes to cover it. The area of one face of a 20 inch cube is 400 square inches. There are 144 square inches in a square foot. So if the area to be covered is rectangular, its the sides are multiples of 20 inches, you could place 144 of the boxes on that rectangle to cover it. If you are talking about cutting the boxes open and using all 6 faces, that's another story. 1/6 of 144 is 24, so 24 boxes opened up have a total area of 400 square feet, but unless you are allowed to cut the boxes further into 20 inch squares, it might be difficult to get them to fit together to cover any reasonably shaped 400 square foot area.
