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 is surface area?

Back

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

Front

How do you find the surface area of a cylinder?

Back

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

Front

What is the surface area of a cube with side length 4 cm?

Back

Surface Area = 6s² = 6(4)² = 96 cm².

Front

If a rectangular prism has dimensions 3 cm, 4 cm, and 5 cm, what is its surface area?

Back

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

Front

What is the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

How do you calculate the surface area of a cone?

Back

Surface Area = πr(r + l), where r = radius and l = slant height.

Front

What is the surface area of a triangular prism with a base of 6 cm, height of 4 cm, and length of 10 cm?

Back

Surface Area = 12 cm² (base area) + 40 cm² (lateral area) = 52 cm².

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface, while volume measures the space inside the object.
