This is the concept of volumes of solid figures;
To calculate for the volume of material required we calculate for the volume of the pyramid;
volume of the pyramid is given by:
volume=(length*width*height)/3
but in our case the base of the pyramid is square, therefore:
length=width=2 ft
height=6 ft
hence;
volume=(2*2*6)/3
volume=8 ft^3
The answer is 8 ft^3
-2x+3y+3. Just add the similar terms
-64/3 divide -64 by 3
-21.33333333333333333
or
-21 1/3
.25/65
(1/4)(1/65)
4*65=260
=1/260
24.5 should be the missing number. 13.5 (13 1/2) + 5.5 is 19. 19 + 5.5 is *24.5*. 24.5 + 5.5 is 30. Basically, you go up by 5.5 every number.
