A cubed shape paper weight is being shipped in a box across the county. It has a mass of 11,769 grams the cube is made from lead glass that has a density of 3.487 grams per cubic cm. what are the dimensions of the paper weight? how does this effect the size of the box? please show work, i want to know how to do it, not just the answer lol

We can use the density formula to find the volume of the paper weight, and then use the volume formula for a cube to find its dimensions.

Density formula: Density = Mass / Volume
Volume formula for a cube: Volume = Length x Width x Height

Let's start by finding the volume of the paper weight:

Density = Mass / Volume
3.487 g/cm^3 = 11,769 g / Volume
Volume = 11,769 g / 3.487 g/cm^3
Volume = 3,375.1 cm^3

Now we can use the volume formula for a cube to find its dimensions:

Volume = Length x Width x Height
3,375.1 cm^3 = L x W x H

Since the paper weight is a cube, we know that the length, width, and height are all the same, so we can call this value "x":

Volume = x^3
3,375.1 cm^3 = x^3
x = cuberoot(3,375.1)
x = 14.4 cm

Therefore, the dimensions of the paper weight are 14.4 cm x 14.4 cm x 14.4 cm (or approximately 5.7 inches x 5.7 inches x 5.7 inches).

To determine how this affects the size of the box, we need to consider the dimensions of the paper weight and add padding and space for shipping. Let's assume we add 2 cm (0.8 inches) of padding on each side of the paper weight, and we want to add an additional 2 cm (0.8 inches) of space on each side of the box for shipping. This means that the dimensions of the box would need to be:

Length = 14.4 cm + 2 cm (padding) + 2 cm (shipping) = 18.4 cm
Width = 14.4 cm + 2 cm (padding) + 2 cm (shipping) = 18.4 cm
Height = 14.4 cm + 2 cm (padding) + 2 cm (shipping) = 18.4 cm

Therefore, the box would need to be 18.4 cm x 18.4 cm x 18.4 cm (or approximately 7.2 inches x 7.2 inches x 7.2 inches) to accommodate the paper weight with padding and shipping space.
