so, you can't do any basic calculations anymore ? turned into a true couch potato/vegetable ?

the volume of a block is

length × width × height.

similar to the 2 dimensional problem of the area of a rectangle : length × width.

now we have one more dimension. that's all.

2x-y=4 3y-3x=6 How do I graph this

bezimeni [28]

Step-by-step explanation:

Put y's on the one side and divided by what they have in the front so it would be

y=2x-4

and

y=x+2

and they y intercept for first one is -4

and slope is 2 which it goes up twice and goes right once because its positive

second one, y intercept is 2

If the volume of a rectangular pyramid is 150 inches cubes ,what is the volume of a prism with the same demensions

Ugo [173]

$\bf \stackrel{\textit{volume of a pyramid}}{V=\cfrac{Bh}{3}}\qquad \qquad \stackrel{\textit{volume of a rectangular prism}}{V=Bh}\qquad \begin{cases} B=base~area\\ h=height \end{cases}$

so let's notice, the volume of the rectangular prism is really 3 times as much of that of a pyramid with the same Base and Height.

so if the pyramid has a volume of 150, the prism will have volume of 3*150.
