Answer:
The mass of the second cube is about 1085.07 grams.
Step-by-step explanation:
I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.
First, find the density of this cube:

where d is density, m is mass, and v is volume.
We have one of those, but we also need volume. The volume of a cube is just:

where a is the length of a side.

The volume of this cube is 1.728cm³. Now, you can find the density;

The density of this material is about 8.68 grams per cubic centimeter.
Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:

The volume is 125cm³. Given the density and the volume, you can calculate the mass:

The mass of the second cube is about 1085.07 grams.
Answer to one im pretty sure is 136.4 degrees and to number 2 is a parallelogram (rectangle or square) you know because the side AD is equal to BC and AB is equal to DC
The orthocenter of an obtuse triangle always lies : C. On the outside of the triangle
<span>Attitude of an obtuse triangle will not go through the midpoint line of the triangle and the three points of the triangle will intersect with each other at some point, so it must lies outside of the triangle</span>
