V = π (D²/4) x L
The volume of the 3-D solid is 120 cubic units, assuming that the 3-D solid is in the form of a cuboid (brick-shaped). The volume of a cuboid is the product of its length, width, and height.
D = M/V Density = Mass divided by Volume
To calculate the volume of a pipe in liters, first determine the internal diameter (d) and length (L) of the pipe. Use the formula for the volume of a cylinder: ( V = \pi \times (r^2) \times L ), where ( r ) is the radius (d/2). Convert the volume from cubic meters to liters by multiplying by 1,000 (since 1 m³ = 1,000 liters).
Calculate the (diameter of the pipe (D) divide by 2) squared X pi * length and this will give you the volume. eg Volume = (D/2)2 X Pi X Length. (or R2 X Pi X Length) (Use 3.14159265359 as an approximation for Pi.) In practice, 11/14 Times Diameter is used in lieu of (R2 X Pi) as a quick and dirty but near enough approximation.

The formula for density is d = density m = mass v = volume
To calculate density, divide the object's mass by its volume. The formula for density is Density = Mass / Volume. Density is a measure of how much mass is contained in a given volume.
The main two tools are mass and volume D=mass/volume
The density is the ratio between the mass and volume: d=M/V.
D = M/V Density = Mass divided by Volume
the answer is 30 times 4= 120yd
You can calculate the volume of the mass by dividing the mass by the density. The formula to calculate volume is volume = mass / density. This formula allows you to determine the space an object occupies based on its mass and density.
H = D sin ( ((2*pi*V.k)/V.t) - pi/2) + D Here: D = Diameter of the cylinder V.k = The known volume of the liquid V.t = The total volume of the cylinder H = The height of the liquid.
Quantity of mass (eg grams) in a standard volume (eg cubic centimeter). Weigh something, measure or calculate its volume, and then divide the weight by the volume. d = w/v
You have to use the density equation... D = M / V D= density M= mass V= volume You have to find the volume of your water. Since you know your density the only thing left to find out is the mass. Just solve for it by multiplying the volume times the density.
