(L + W) x 2 (8 + 3) x 2 = 11 x 2 = 22m
A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
Perimeter is just twice the sum of length and width, in this case 2 x 11 m ie 22 m.

Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
If you put an ant down on the rectangle and start him walking along the line, the 'perimeter' is the distance he has to walk in order to get back to where he started, if he stays on the line. If you put him down on a corner of this one, he has to walk (8m + 3m + 8m + 3m) = 22m. That's the perimeter.
Well, honey, to find the perimeter of a rectangle, you add up all the sides. So, for your rectangle with sides of 12m and 8m, you simply add 12 + 12 + 8 + 8 to get a perimeter of 40 meters. Voila!
If you mean an area measuring 3m x 8m, the answer is 22m !
it is the amount of squares.

To neutralize the 25ml of 3M acid, you would need to find the number of moles of acid present, which is 25ml * 3M = 75 millimoles. Then, you would need the same number of millimoles of the 8M base to neutralize it, so you would need 75 millimoles / 8M = 9.38ml of the 8M base.
8m*5m=40 m2 The area of the rectangle is 40m2
