The surface area of a cube is 216 sq.cm. What is it’s volume

1 answer:

7 0

First we need to find it’s length/width which we can do by dividing 216 by the amount of faces it has and then divide that result by 2

216/6=36
36/2=18

And volume is pretty much just 3 times that answer

3(18)=54

The volume is 54 cm^3

Answer:

US$ 132.45

Step-by-step explanation:

See attachment for the missing table.

Given:

Richard’s checking account balance at the beginning of the week = $57.34

<u>Richard’s account balance at the end of the week from the given table:</u>

Deposits of the week = US$ 163.75

Expenses of the week = Groceries + Credit card bill + Gas

Expenses of the week = 25.37 + 50 + 13.27

Expenses of the week = US$ 88.64

Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week

Replacing with the real values:

Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64

=US$ 132.4
