Question

Solve the problem. Use π = 3.14 when necessary. At $4.50 per m3, how much will it cost to fill an ice chest with dimensions of 3.2/3m x 7m x3.1/3m

Round to the nearest cent.

A. $385.00

B. $201.67

C. $350.00

D. $808.50

Answer 1

do you mean the dimensions are 3 2/3 m by 7 m by 3 1/3 m?

Answer 2

yes

Answer 3

Is the ice chest rectangular or round? If it isn't round, why do we need pi?

Answer 4

rectangular

Answer 5

The volume is given by Vol= height times width times depth. Multiply it out to get the total volume in cubic meters. Multiply the volume by the cost per cubic meters to get the total cost.

Answer 6

7.71m^3 x 4.50m3 = 34.69m^3

Answer 7

Where did you get 7.71 cubic meters? my number was much larger than that.

Answer 8

ya I got 383.80

Answer 9

you got 383.80 for what?

Answer 10

(3.66 m) x (7 m) x (3.33 m) = 85.31 x 4.50m3

Answer 11

much better.

Answer 12

and rounded it off 383.80
is that right

Answer 13

Well, I got 85.56 x 4.50 = 385
just some rounding errors. I multiplied
\[\left( 11 \over 3 \right)\times7 \times \left( 10 \over 3 \right)=\left( 770\over 9 \right)\]

Answer 14

I don't mean rounding errors, I mean a difference because of rounding

Answer 15

ok thank you for help me understand how to this.

Answer 16

you're welcome
