160 in cubed

314 m cubed

384 cm squared

44.57962667 or 45 cm cubed

Step-by-step explanation:

The volume of a square is V=a^3

If you plug in 3.8 for a you would get V≈54.87

The volume of a cylinder is V=π(r^2)h

If you plug in the given measures and solve you get 442.3475 or 442

Do the same for #3 and get 226.08 or 226

The volume of a right triangular prism is the (area of the base times it's height) divided by 3. You would get 8 x 5 =40 40 x 6 is 240 240/3 is 80

Do the same for #5 and get 160

Find area of base, circle, with A=pi times r squared and get 78.5. multiply by its height (12, solve for height with Pythagorean theorem) and get 924. Divide by three and get 314.

A square's area is base times height so it would be 64. a cube has 6 sides so do 64 times 6 and get 384.

Break down the prism into 6 rectangles. Find the area of each rectangle and add them up to get 126.

The formula for SA of a cylinder is A=2πrh+2πr^2

Plug in the given values and get 923.16 or 923

Do the same for #10 and get A≈1123.12 or 1123

The volume of a sphere is V=(4/3)πr^3

Plug in 2.2 for r and get 44.57962667 or 45

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
