Suppose the base of the prism was a rectangle of sides I and w. Type a formula for the volume of the prism using i, w and h
tester [92]

Answer: V = l  w  h

Step-by-step explanation:

Hi, to answer this question we have to apply the formula for the volume of a rectangular prism.

Volume of a rectangular prism (V) = Length x Width x Height

Replacing with the values given:

V = l w h

All values are multiplied (didn’t use x as a multiplication symbol to avoid confusion)  

Feel free to ask for more if needed or if you did not understand something.

Volgvan

Answer:

If the numbers were the same, they'd both be 61

So, try 60 and 62.

x + x+2 = 122

2x = 120

x = 60

Hope that helps!

Tony's fish tank is a right rectangular prism 50 \,\text{cm}50cm50, space, c, m long by 25\, \text{cm}25cm25, space, c, m wide.
Svetlanka [38]
The volume of the prism is calculated by multiplying the length, L, width,W, and depth or height, H. 
                                 V = L x W x H
Fish tank:
                                V = 50 cm x 25 cm x 25 cm 
                                     = 31250 cm³
Depth of the water in tank (with castle - without castle)
                                   d = 57.5 cm - 48 cm = 9.5 cm
Volume of the caste: 
                                V = 9.5 cm x 50 cm x 25 cm = 11875 cm³

Cost of the pool with interest rate is $9250.56.
3yr*12mo=36mo
$9250.56/36mo=256.96$/mo
