A triangular pyramid has the same base and height as a triangular prism. The volume of the pyramid is 26 cubic centimeters. What is the volume of the triangular prism?

Answers

Answer 1

Answer: The formula for the volume of a triangular pyramid is:

V=1/3AH (where A=area of the base and H=height)

The formula for the volume of a triangular prism is:

V=AH (where A=area of the base and H=Height)

Since the base and the height are the same in this problem for both the prism and the pyramid, solving for the volume of the prism is simple.

Looking at the formulas, you'll see that the volume of the pyramid (assuming that both the height and the area of the base are the same) is 1/3 the volume of the prism.

V(pyramid)=1/3V(prism)

Now lets input the volume of the pyramid

26cm³=1/3 V(prism)
Divide both sides by 1/3
78cm³=V(prism)

Answer=78cm³

b) yard 1: 64yd. yard 2: 60yd

c) yard 2

d) yard 1

Step-by-step explanation:

area=base×height

perimeter=2×base+2×height

Answer:

a) 220 yd for the OLD HOUSE

a) 225 yd for the CURRENT HOUSE

b) 64 for the OLD HOUSE

b) 60 for the CURRENT HOUSE

c) the CURRENT HOUSE has more room for the kids (the area is bigger (area=space inside)

d) the OLD HOUSE requires more fence, because the perimeter is bigger (perimeter=the outside of the square)

#1).
Surely, now that you're in middle school, you know that the volume of a cube is

   (the length of the edge)-cubed
OR
   (length of the edge) x (length of the edge) x (length of the edge) .

The length of the edge of the cube in the picture is 9-ft.
To find the volume of the cube, use the formula that I just reminded you of.

#2).
Twenty minus nine is written as (20 - 9).
Seven is written as (7) .
Their product is written as (20 - 9) x (7) .

To find the value of the expression:

Do the subtraction inside the parentheses: (20 - 9) = 11
So now the whole expression is
   (11) x (7)
Now do the multiplication:
   11 x 7 = 77
