In question, we are going to answer few questions.
00:03
The first one.
00:04
We are given the cube dimension, a is equal to 2 .55 centimeter, and the mass is given as 56 .7 gram.
00:13
So the density row will be equal to m by v, or we can write it's m by a cube.
00:19
A cube will be the volume of the cube.
00:22
So 56 .7 divide a cube is 2 .55 centimeter and its power 3.
00:27
Now if you solve this then we get around 3 .42 gram per centimeter cube in the b part we are given the object mass m is equal to 45 .6 ounce so we can convert this into gram 45 .6 multiply we need to multiply by 28 .35 to convert it into gram we get around 1 to 992 .7 gram and the volume v is given as 2 .65 gallon.
01:02
Now we will convert this into liter first so 2 .65 multiply 2 .65 multiply 7 .7 sorry 3 .785 we need to multiply by 3 .785 to convert gallon into liter.
01:20
Now we will convert this later into ml so we will multiply by 10 to the power 3 so it comes out to be 9 .689 multiply 10 to the power 3 ml.
01:31
Now we can find the density row that is equal to m by v.
01:35
So m is 1292 .74 gram divide the density the volume is 9 .689 multiplied 10 to the power 3...
