Answer is 512 cu.ft.
Volume of a cube is length x width x height
So 8 x 8 x 8 = 512
25, 65, and y make a right triangle. use a^2 + b^2 =c^2.
so...
y^2 + 25^2 = 65^2
y^2 + 625 = 4225
y^2 = 3600 take the square root of both sides
y=60
That's an easy one! The year would be Monday Janurary 27th, 3000 and it would be the year of the monkey!
To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.
