What is the volume of the prism?

SOVA2 [1]

Answer:

148 in³

Step-by-step explanation:

The equation for the volume of a cube is $V = a^{3}$

Here, $a = \frac{1}{3}$ .

$V=\frac{1}{3} ^{3}$

$V = \frac{1}{27}$

So, the volume of each cube is $\frac{1}{27}$ in.

The prism is filled completely with 3996 of these cubes.

$3996*\frac{1}{27} = 148$

The volume of the prism is 148 in³.

Eva will send thank you cards to the 26 people who came to her birthday party and to any others who send presents by mail. Let m

mars1129 [50]

Answer:

$t = 26 + m$

Step-by-step explanation:

We are given the following in the question:

Number of people who came to Eva's party = 26

Number of people who send present by mail = $m$

Let $t$ represent the total number of thank you card Eva needs to send.

Eva will send a thank you card to everyone who attended the party and send the gift by mail.

Number of thank you card = Number of people who attended the party + Number of people who send the gift by mail

Thus, we can write the the equation:

$t = 26 + m$

is the required relation between m and t.
