Cubes Investigation Nets & Surface Area

Cube Nets How many are there? 11

Draw the net of a 4 cm cube Remember: 6 congruent faces measuring 4 cm by 4 cm arrange in one of the 11 options that will form a cube when folded

Create a die with a given net

Is it the net of a cube? No!

What is the surface area? 5 cm a)25 cm 2 b)125 cm 2 c)150 cm 2 d)200 cm 2 There are 6 congruent faces. Each face has an area of 25 cm 2 So six faces will have an area of 150 cm 2

What is the surface area? 4 cm a)12 square inches b)16 square inches c)64 square inches d)96 square inches There are 6 congruent faces. Each face has an area of 16 in 2 So six faces will have an area of 96 in 2

What is the length of the edge? Surface Area = 486 m 2 There are 6 congruent faces. Each face has an area of 81 m 2 So each edge has a length of 9 m
