Abox is a cuboid with dimensions 28cm by 15 cm by 20 cm all measured to the nearest centimetre. disc cases are cuboids which measure 1.5 cm by 14.2 cm by 19.cm all measured to the nearest millimetre. show that 17 disc cases, stacked as shown, will definitely fit in the box.

See Below

Step-by-step explanation:

To get volume of cuboid, we multiply the 3 dimensions.

Volume of Box = 28 * 15 * 20 = 8400

Volume of 1 disc case = 1.5 * 14.2 * 19 = 404.7

Volume of 17 disc cases = 17 * 404.7 = 6879.9

Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

understand that i don't know the answers

will someone answer his question
