V=(1/3)Ah
A=a*b for squares and a*b/2 for right triangles

1)
A=6*8.5=51
V=51*12/3=51*4=204in^3

2)
A=12*6=72
V=72*15/3=72*5=360ft^3

3)
A=18*24/2=18*12=216
V=216*35/3=72*35=2520cm^3

4)
A=26*15/2=13*15=195
V=195*38/3=65*38=2470cm^3

5)
A=B=8ft^2
V=8*12/3=8*4=32ft^3

$\huge{\boxed{60\ \text{ft}^{3}}}$

We will assume the tent is in the shape of a triangular prism.

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.

$V=\frac{1}{2}bhl$

Substitute in the known values.

$V=\frac{1}{2}*5*3*8$

Simplify — use multiplication.

$V=\frac{5}{2}*3*8$

$V=\frac{15}{2}*8$

$V=\frac{120}{2}$

Simplify — use division.

$V=\large{\boxed{60\ \text{ft}^{3}}}$

The volume — or in this case, the amount of living space — is $60\ \text{cubic feet}$ .

you mix (5)/(8)of a cup of wheat flour with 1 (3)/(4)cups of white flour. Do you have enough flour for a recipe that calls for 2

swat32

5/8+1 3/4
5/8+7/4(turned into improper fraction)
5/8+14/8=19/8=2 3/8
(Make sure they all have a common denominator so that u will be able to add)Then your answer is an improper fraction so u turn it in to a mixed number and 2 1/2 is the same as 2 4/8 and you have 2 3/8 therefore,
no you do not have enough flour you need 1/8 of a cup more.
