Surface Area of 3D Solids

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 + l(s1 + s2 + s3), where b = base, h = height of the triangle, l = length of the prism, s1, s2, s3 = lengths of the triangular sides.

Front

What is the formula for the surface area of a cylinder?

Back

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

Front

What is the formula for the surface area of a sphere?

Back

Surface Area = 4πr², where r = radius.

Front

What is the formula for the surface area of a cone?

Back

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

Front

What is a prism?

Back

A solid object with two identical ends and flat sides. The sides are parallelograms.

Front

What is a pyramid?

Back

A solid object with a polygonal base and triangular faces that meet at a common point (the apex).

Front

How do you find the surface area of a composite solid?

Back

Calculate the surface area of each individual solid and then sum them up, subtracting any overlapping areas.

Front

What is the difference between lateral surface area and total surface area?

Back

Lateral surface area includes only the sides of the solid, while total surface area includes the sides and the bases.

Front

What is the surface area of a cube?

Back

Surface Area = 6a², where a = length of a side.
