The density of copper is 8.96 g/cm3 . You have three different solid samples of copper. One is rectangular with dimensions 2.3 cm x 3.1 cm x 8.0 cm. The second is a cube with edges of 3.8 cm. The third is a cylinder with a radius of 1.5 cm and a height of 8.4 cm. Calculate the mass of each sample.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

i wish i could you, i have no idea how to answer this

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2
