Surface Area!!!

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional object that can be folded to form the object.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

Calculate the surface area of a rectangular prism with dimensions: length = 5 cm, width = 3 cm, height = 4 cm.

Back

Surface Area = 2(5*3 + 5*4 + 3*4) = 2(15 + 20 + 12) = 2(47) = 94 cm².

Front

What is the surface area of a cube with side length 6 cm?

Back

Surface Area = 6 * (side length)² = 6 * (6)² = 6 * 36 = 216 cm².

Front

If a rectangular prism has a length of 10 m, width of 5 m, and height of 2 m, what is its surface area?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 m².

Front

What is the surface area of a cylinder with a radius of 3 cm and height of 7 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(7 + 3) = 2π(3)(10) = 60π cm².

Front

Define surface area.

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

What is the surface area of a rectangular prism with dimensions: length = 8 m, width = 4 m, height = 3 m?

Back

Surface Area = 2(8*4 + 8*3 + 4*3) = 2(32 + 24 + 12) = 2(68) = 136 m².

Front

How do you find the surface area of a triangular prism?

Back

Surface Area = (Base Area * 2) + (Perimeter of Base * Height).

Front

What is the surface area of a sphere with a radius of 5 cm?

Back

Surface Area = 4πr² = 4π(5)² = 100π cm².
