I don't even know where to begin to solve this problem please help
A 6.5 g piece of copper was rolled out into a thin sheet measuring 24.0 cm x 18.0 cm. The density of copper is 8.90g/cm3
1. Calculate the volume of the sheet of metal
2. Calculate the thickness of the sheet of copper
well volume = mass/density = 6.5/8.9
=.73 cm^3
I got .0017 for t
V = Volume = length*width * thickness =L w t
V = 24 * 18 * t
6.5 mass = V*density = 24 * 18 * t * 8.9
so
t = 6.5 /(24*18*8.9)
then
V = 24 * 18 * t
i think i understand is the volume 57.85
Certainly! I'll guide you through the steps to solve each part of the problem.
1. To calculate the volume of the sheet of metal, you can use the formula:
Volume = Length x Width x Height
In this case, the length is 24.0 cm and the width is 18.0 cm. We need to find the height or thickness of the sheet. Since the sheet was rolled out, the thickness is the unknown.
2. Now, let's calculate the thickness of the sheet of copper. We can use the formula:
Density = Mass / Volume
The density of copper is given as 8.90 g/cm³, and the mass of the sheet is 6.5 g. We know the volume from the previous step, so we can rearrange the formula and solve for thickness:
Thickness = Mass / (Density x Length x Width)
Now let's plug in the given values and calculate the answers step by step.
1. Volume:
Volume = Length x Width x Height
Volume = 24.0 cm x 18.0 cm x Height
2. Thickness:
Thickness = Mass / (Density x Length x Width)
Thickness = 6.5 g / (8.90 g/cm³ x 24.0 cm x 18.0 cm)
Using a calculator, we can perform the calculations:
1. Volume = 24.0 cm * 18.0 cm * Height = 432.0 cm³
2. Thickness = 6.5 g / (8.90 g/cm³ * 24.0 cm * 18.0 cm) ≈ 0.012 cm
Therefore, the volume of the sheet of metal is 432.0 cm³, and the thickness of the sheet of copper is approximately 0.012 cm.
