1what is the volume, in cubic feet, of the
square pyramid below? use the formula
v= 1/3bh.
12 feet
7 feet
a 168 cubic feet
b 196 cubic feet
c 294 cubic feet
d 588 cubic feet

The volume of square pyramid is 196 cubic feet

Step-by-step explanation:

Given as :

The side of square pyramid = side = 7 feet

The height  of square pyramid = 12 feet

So , The formula for Volume of square  pyramid

Volume =

Or,   Volume =     cubic feet

Or,   Volume =  

Or,   Volume = 49 × 4 = 196 cubic feet

Hence The volume of square pyramid is 196 cubic feet  Answer

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
