What is 40 cubed?

To cube a number means simply to multiply that number by itself 3 times. To work out 40 cubed you would simply go:403 = 40 x 40 x 4040 x 40 = 1,6001,600 x 40 = 64,000403=64,000Therefore, 40 cubed equals 64,000.The phrase "multiply that number by itself 3 times." can cause confusion.Sometimes, instead of multiplying it thrice (the number itself) others, due to confusion, just multiply the number by 3... take note it's cube...What do you get if you multiply 40 by itself once?Nearly everyone would say 1,600 which is 40².Multiply that by 40 then seems to mean multiply the answer by 40, giving 64,000 which is then 40 multiplied by itself twice!Of course some people will say it doesn't matter how many times you multiply 40 by itself you'll always get 1,600.Just think of 40³ as meaning 3 40s multiplied together and you should avoid any problems.
