i need help on this question it is very hard for methanks if u help!i need hellp
Volume = (Area of Base) x (Height)
Height = 72 cm
The base is a trapezoid -- Area of Base = ½·(height)·(base1 + base2)
= ½·(65)·(80 + 50)
= 4225
Volume = (4225) x (72) = 304.200 cubic centimeters.
can you also try to do the other ones?
10) if we lay the cube flat, the rectangle with corners A, B becomes 8*6. to find the diagonal would be like finding the third side of a right triangle. 8^2+6^2 = c^2 => c = 10 => the shortest distance is 10 units.
