Homework Help: Algebra - volume

Posted by Sylvia on Wednesday, February 27, 2013 at 6:23pm.

I can't draw the shape here, but the picture is of a 3-sided pyramid. One side of the base is 10", another side of the base is 3", and the height is 15". I need to find the volume and round to the nearest whole number.

just giving two sides of the base does not help, unless the base is a right triangle. Then we know the base has area 1/2 * 10 * 3 = 15

Then the volume of the pyramid is 1/3 Bh = 1/3 * 15 * 15 = 75
