D = 0.7857 g/cm³
V = 28.58 mL
m = ?
d = m / V
m = d · V
V = 28.58 mL = 28.58 cm³
m = 0.7857 g/cm³ · 28.58 cm³
m = 22.4553 g

The volume of a rectangular prism is 72 cubic centimeters. The prism is 2 centimeters wide and 4 centimeters high. What is the l

skelet666 [1.2K]

Answer:

The length of prism is 9 centimetres.

Step-by-step explanation:

Given:

The volume of a rectangular prism is 72 cubic centimeters.

The prism is 2 centimeters wide and 4 centimeters high.

Now, to find the length of prism:

Let the length be $l$ .

Width = 2 centimeters.

Height = 4 centimeters.

Volume = 72 cubic centimeters.

So, putting the formula to get the length of prism:

$Volume = length\times width\times height$

$72=l\times 2\times 4$

$72=l\times 8$

Dividing both sides by 8 we get:

$9=l$

Length = 9 centimetres.

Therefore, the length of prism is 9 centimetres.
