The area of the base of a rectangular prism is 36 cm2. The height of the prism is 3 5/6 cm. What is the volume of the prism?

Lilit [14]

Answer: The correct option is (C) 36 cm².

Step-by-step explanation: We are given to find the volume of a rectangular prism with base area 36 cm² and height $3\frac{5}{6}~\textup{cm}.$

We know that the volume of a rectangular prism with base area b sq. units and height h units is given by

$V=bh.$

Here,

base area, b = 36 cm²

and

height is

$h=3\dfrac{5}{6}=\dfrac{23}{6}~\textup{cm}.$

Therefore, the VOLUME of the given prism will be

$V=bh=36\times \dfrac{23}{6}=6\times 23=138~\textup{cm}^3.$

Thus, the volume of the given rectangular prism is 36 cm².

Option (D) is CORRECT.

Y varies directly as x. if x =5 when y=12. find x when y=30

boyakko [2]

X = 5 ... y = 12
x = ? ... y = 30

If you would like to know the value of x when y = 30, you can calculate this using the following steps:

5 * 30 = x * 12
x * 12 =150 /12
x = 150 / 12
x = 12.5

The result is 12.5.
