Density problems maths
WebFree Density Calculator - calculate density step by step. Math can be an intimidating subject. Each new topic we learn has symbols and problems we have never seen. WebJul 11, 2024 · Density = Mass/Volume. Step 1: Calculate Volume. In this example, you are given the dimensions of the object, so you have to calculate the volume. The formula for volume depends on the shape of the object, but it's a simple calculation for a box: Volume = length x width x thickness. Volume = 10.0 cm x 10.0 cm x 2.0 cm. Volume = 200.0 cm 3.
