Nets and Surface Area of Rectangular Prisms

Front

What is a net in geometry?

Back

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

Front

What 3D solid does this net create?

Back

Rectangular Prism

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 surface area of a rectangular prism with dimensions 5 in, 4 in, and 3 in?

Back

Surface Area = 2(5*4 + 5*3 + 4*3) = 2(20 + 15 + 12) = 2(47) = 94 in².

Front

What is the total surface area of a rectangular prism?

Back

The total surface area is the sum of the areas of all six faces of the prism.

Front

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

Back

Calculate the area of each face and sum them up, or use the formula: Surface Area = 2(lw + lh + wh).

Front

What is the surface area of a rectangular prism with a length of 10 cm, width of 5 cm, and height of 2 cm?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 cm².

Front

What is the surface area of this figure? (Assuming dimensions are given)

Back

800 cm².

Front

What is the surface area of a rectangular prism with dimensions 6 m, 4 m, and 3 m?

Back

Surface Area = 2(6*4 + 6*3 + 4*3) = 2(24 + 18 + 12) = 2(54) = 108 m².

Front

What is the surface area of a rectangular prism with a length of 12 in, width of 6 in, and height of 4 in?

Back

Surface Area = 2(12*6 + 12*4 + 6*4) = 2(72 + 48 + 24) = 2(144) = 288 in².
