Answer:

  • 109.375 cm³

Step-by-step explanation:

<u>The volume of the cube is:</u>

  • V = a³ = 5³ = 125 cm³

<u>The volume of the cut prism:</u>

  • V = Bh, B- area of the base, h- height

The base is a right triangle with legs of 2.5 each.

<u>The volume is:</u>

  • V = 1/2*2.5*2.5*5 = 15.625 cm³

<u>Required volume of the solid is the difference of the above volumes:</u>

  • 125 - 15.625 = 109.375 cm³

Answer:

7. ○ ∆<em>ACB</em> ≅ ∆<em>DFE</em>

6. ○ \displaystyle 43°

5. ○ \displaystyle ∠M ≅ ∠S

4. ○ \displaystyle octagon

3. ○ \displaystyle squares

2. ○ \displaystyle rhombus

1. ○ \displaystyle equilateral\:triangle

Step-by-step explanation:

7. Everything is in correspondence with each other, so just follow the pattern in the order the they were originally.

6. All angles correspond with each other, so just follow the pattern.

5. All segments and angles correspond with each other, so just follow their patterns.

4. An <em>octagon</em><em> </em>has eight sides, a triangle has three sides, a <em>hexagon</em> has six sides, and a <em>pentagon</em><em> </em>has five sides. With this being stated, you have your answer.

3. In a previous lesson, we confirmed that <em>all squares </em><em>are</em><em> </em><em>rectangles</em><em> </em>because it is a quadrilateral with four right angles.

2. This is obviously a rhombus because it is a quadrilateral with four congruent angles and sides.

1. An EQUILATERAL TRIANGLE is a regular polygon because they have three congruent angles and sides.

I am joyous to assist you anytime.
