Surface area rectangular prisms and cubes

Front

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

Back

Surface Area = 6 * (side length)^2 = 6 * (4 cm)^2 = 96 cm².

Front

What is a rectangular prism?

Back

A 3D shape with 6 faces, all of which are rectangles.

Front

How many faces does a cube have?

Back

A cube has 6 faces.

Front

What is the difference between a rectangular prism and a cube?

Back

A rectangular prism can have different lengths, widths, and heights, while a cube has all sides equal.

Front

What is the surface area of a rectangular prism with length 5 cm, width 3 cm, and height 2 cm?

Back

Surface Area = 2(5*3 + 5*2 + 3*2) = 2(15 + 10 + 6) = 2(31) = 62 cm².

Front

What is a net of a 3D shape?

Back

A net is a 2D representation that can be folded to form a 3D shape.

Front

Identify the 3D shape that has all triangular faces.

Back

Triangular Pyramid.

Front

What is the surface area of a cube with a side length of 10 cm?

Back

Surface Area = 6 * (10 cm)^2 = 600 cm².

Front

What is the volume of a rectangular prism with length 4 cm, width 3 cm, and height 5 cm?

Back

Volume = length * width * height = 4 cm * 3 cm * 5 cm = 60 cm³.
