Abby has a jewelry business. She uses small square boxes to ship her homemade rings to stores to sell. The ring box measures 12 in. on all sides. The shipping box she uses is in the shape of a rectangular prism and has a length of 1012 in., a width of 8 in., and a height of 3 in.

She needs to determine the volume of the shipping box and total number of ring boxes that will fit in her shipping box.

You already know that the ring box, which is the same as a unit cube, has an edge length of 12 in.

What is the volume of the unit cube, the ring box, that will fill the shipping box?

Volume of Shipping box= lenghth × breadth × height

Volume of ring box= side × side × side

Step-by-step explanation:

Volume of ring box = 12×12×12

=1728 units

Volume of shipping box= 1012×8×3

=24288 units

number of ring boxes in shipping box= 24288/1728

= 14.

Hope am correct

Thanks

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
