Volume = 1/3 * area of base * height

=1/3 * 11^2 * 15

= 605 cm^3 Answer

So to find the volume of a square pyramid, the formula is 1/3B2h or Base squared times height divided by 3 because of the triangular pyramid. So the base is 11, the height is 15 so 11 squared is 121 and the height is 15, so 121 times 15.

121 x 15= 1,815.

Now we divide by 3 because of the formula, so 1,815 divided by 3 is...

1,815 / 3= 605 cm squared!

Explain why you rename 4 1/4 to find 4 1/4- 3/4

Hitman42 [59]

Answer:

Because it is a mixed fraction and it should be renamed in order to solve your problem, for the other one CAN NOT be converted into a mixed fraction.

The scale on a trail map is 0.5 cm : 1 km. The straight distance between 2 huts on the trail is 16.9 cm. What is the actual dist

sesenic [268]

We have been given that the scale on a trail map is 0.5 cm : 1 km. The straight distance between 2 huts on the trail is 16.9 cm. We are asked to find the actual distance between 2 huts.

We will use proportions to solve our given problem.

$\frac{\text{Actual length}}{\text{Scale length}}=\frac{\text{1 km}}{\text{0.5 cm}}$

$\frac{\text{Actual length}}{\text{16.9 cm}}=\frac{\text{1 km}}{\text{0.5 cm}}$

$\frac{\text{Actual length}}{\text{16.9 cm}}\times \text{16.9 cm}=\frac{\text{1 km}}{\text{0.5 cm}}\times \text{16.9 cm}$

$\text{Actual length}=\frac{\text{1 km}}{\text{0.5}}\times \text{16.9}$

$\text{Actual length}=33.8\text{ km}$

Therefore, the actual distance between both huts is 33.8 km.
