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

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M
a_sh-v [17]

Answer:

16 mm  

Step-by-step explanation:

Since ABC is an equilateral triangle, all three sides are the same length.  The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us

x + x + x = 96

Combining like terms,

3x = 96

Dividing both sides by 3,

3x/3 = 96/3

x = 32

Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.
