When asked to work out the lengths of its edges and its surface area.
If you are given the volume, then you do not need to work it out!
For this, you can work out the volume of the cylinder of sand you need to fill. But you'll also need to know the density of the sand to convert this volume into weight.
This can not be worked out as volume is bassically a measure of size and so you need the dimensions to work this out, however if you mean density than you can not work that out without knowing the weight and volume.
To calculate the volume of water in a tank, you need to know the tank's shape and dimensions. For a rectangular tank, multiply the length, width, and height (Volume = Length × Width × Height). For a cylindrical tank, use the formula Volume = π × radius² × height. Ensure all measurements are in the same units to obtain the volume in cubic units.
To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.

If you are given the volume, then you do not need to work it out!
If you don't know this you can work it out from the units: Density = kg/m^3 (kilograms per metre cubed) Mass is measured in kilograms Volume is measured in metres cubed You therefore need mass and volume to work out density.
You can't without more information, a kg is a unit of weight or mass and a cubic meter is a measure of volume. You can work out what a cubic meter of SOMETHING will weigh in kgs - but you need to know what that SOMETHING is (you need to know its density).
For this, you can work out the volume of the cylinder of sand you need to fill. But you'll also need to know the density of the sand to convert this volume into weight.
tablespoons are a measure of volume, lb (pounds) is a measure of weight, thus the two can not be equated directly you need to know - tablespoons of WHAT before you can work out how many will be needed to make a pound of that WHAT. i.e to convert volume into weight you need to know the dentistry of the material being measured.
You also need to know the weight, to work that out. The information given will only give you the volume.
Weight vs volume. PLace object in container already full of water. Measure volume of liquid displaced. weight object. weight divided by volume equals density
Volume = pi*radius2*height
get with him in a partner or something, with homework or something. if that doesnt work, just say you need to talk about something in private. i know its embarrassing, but you have to if you want to tell him
