11 - 8 and 1/2 = 2 and one half
The volume of a cube is the length of one of its sides (since all sides have equal length, for a cube) cubed. To find the side length from the volume, find the cubic root - in this case, it is easy as the cubic root of 8 is exactly 2. Now, because the centre of the cube is halfway between one side and its opposite, and one side being its base, the distance from the centre to that base will be half of its side length. For this cube, this is 2/2 which is 1.
Half of them.
Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.
Perimeter = 2*(Width + Length) So 40 = 2*(8 + Length) 20 = 8 + Length Length = 12.
11 - 8 and 1/2 = 2 and one half
five-eighths (5/8) of a cup. To find half of one and a quarter we need to find half of one and then half of a quarter and then add them togerther. Half of one is a half. Half of a quarter is one eighth. So the answer is ahalf and an eighth. 1/2 + 1/8. Now one half is the same as four eighths so we have 4/8 + 1/8. Four eighths plus one eighth is five eighths. = 5/8

Perimeter = 8 x (length of one side)
A minim.
Half of them.
Find the length of the hypotenuse of a right triangle whose legs are 8 and 15 units in length.
Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.
I guessed and the answer is 8
8 and one quarter add 8 and a half = 16
no because 4/8 is one half
Perimeter = 2*(Width + Length) So 40 = 2*(8 + Length) 20 = 8 + Length Length = 12.
