Answer 1

Answer:

$\Large \boxed{\sf 109.375 \ cm^3}$

Step-by-step explanation:

Volume of remaining solid = Volume of cube - Volume of triangular prism

Volume of cube:

$5^3=125$

Volume of triangular prism:

$2.5 \times 2.5 \times 0.5 \times 5=15.625$

Volume of remaining solid:

$125-15.625=109.375$

Answer 2

Answer:

• 109.375 cm³

Step-by-step explanation:

The volume of the cube is:

• V = a³ = 5³ = 125 cm³

The volume of the cut prism:

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

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

The volume is:

• V = 1/2*2.5*2.5*5 = 15.625 cm³

Required volume of the solid is the difference of the above volumes:

• 125 - 15.625 = 109.375 cm³
