Look at the triangular prism. Work out the volume of the prism.
xz_007 [3.2K]

Answer:

See explanation

Step-by-step explanation:

The question has missing details, as the diagram of the prism is not shown.

However, I'll solve using a general rule.

The volume of a triangular prism is:

Volume = \frac{1}{2}* b * h * l

Where

b = base

h = height

l = length

Take for instance:

b = 20cm

h = 10cm

l = 5cm

The volume is:

Volume = \frac{1}{2} * 20cm * 10cm * 5cm

Volume = 10cm * 10cm * 5cm

Volume = 500cm^3

Another instance (see attachment).

From the attachment:

b = 4.5cm

h = 5cm

l = 8cm

The volume is:

Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm

Volume = 2.25cm * 5cm * 8cm

Volume = 90cm^3

Vesnalui [34]

Answer:

21 grapes.

Step-by-step explanation:

We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.

First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.

\text{Grapes eaten by Tyrell}=2\times 6

\text{Grapes eaten by Tyrell}=12

Now, we will find half of 6 to find number of grapes eaten by Lucy.

\text{Grapes eaten by Lucy}=\frac{6}{2}

\text{Grapes eaten by Lucy}=3

\text{Grapes eaten by them in all}=6+12+3

\text{Grapes eaten by them in all}=21

Therefore, the three of them eat 21 grapes in all.
