Surface AREA (3/21)

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

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

Back

Surface Area = bh + l1h + l2h + l3h, where b = base, h = height of the triangle, l1, l2, l3 = lengths of the triangular sides.

Front

What units are used to measure surface area?

Back

Square units (e.g., cm², m², ft²).

Front

If a rectangular prism has a length of 5 cm, width of 3 cm, and height of 4 cm, what is its surface area?

Back

94 cm².

Front

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

Back

Surface Area = 6s² = 6(6 cm)² = 216 cm².

Front

How do you find the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r = radius, h = height.

Front

What is the surface area of a triangular prism with a base of 4 cm, height of 3 cm, and slant height of 5 cm?

Back

Surface Area = 6 cm² + 12 cm = 18 cm².

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.

Front

If the surface area of a rectangular prism is 60 cm², what could be its dimensions?

Back

Possible dimensions could be 3 cm x 4 cm x 5 cm.

Front

What is the surface area of a sphere with a radius of 7 cm?

Back

Surface Area = 4πr² = 4π(7 cm)² ≈ 615.75 cm².
