A cuboid made of metal has dimensions 10 cm, 8 cm and 5 cm. The mass of the cuboid is 1.1 kg. Calculate the density of the metal. State the units of your answer.

Step-by-step explanation:

Density is D = M/V, where D = density, M = mass, and V = volume.

First, I would calculate the volume. For the volume, you will multiply all the values you are given along with their units. You would then plug the values you know into D = M/V. Your mass is 1.1kg, so D = 1.1 kg / VYour volume is 400 cm^3, so D = 1.1kg/400 cm^3Keeping the units, you would divide to get a density of 0.00275 kg/cm^3

Hope this helped!

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
