How many square centimeters has the total surface area of this rectangle been reduced

How many square centimeters has the total surface area of this rectangle been reduced

There are three contact surfaces, each contact surface is less than two facets of cube, a total of six facets are less, so 6cm & # 178 is reduced;

How many square centimeters is the surface product of a cuboid made of a cube with an edge length of 1cm?

1 × 1 × 6 = 6 square centimeter

How many square centimetres is the surface area of a cuboid made of five cuboids whose edges are 1cm long?

5*6=30
(5-1)*2=8
30-8=22
22 * 1 * 1 = 22 square centimeters

Three small cubes with edge length of 1cm form a cuboid. The surface area of the cuboid is (). The volume is ()

The length is 3 × 1 = 3
The surface area is (3 × 1 + 3 × 1 + 1 × 1) × 2 = 14 square centimeters
Volume 1 × 1 × 3 = 3 cubic centimeter

A cuboid is made up of six cuboids with 1cm long edges. What is the volume of the cuboid? What is the minimum surface area?

Let the volume of the assembled cuboid be v = 1 * 1 * 6 = 6cm ^ 2
Surface area s = 6 * 1 * 4 + 1 * 1 * 2 = 26 cm ^ 2

The surface area of the cuboid is______ Cm2, volume______ cm3．

Surface area: (4 × 1 + 4 × 1 + 1 × 1) × 2 = 9 × 2 = 18 (square centimeter) or: (2 × 2 + 2 × 1 + 2 × 1) × 2 = 8 × 2 = 16 (square centimeter) volume: 1 × 1 × 4 = 4 (cubic centimeter) answer: the surface area of cuboid is 18 or 16cm2, the volume is 4cm3. So the answer is: 18 or 16, 4

How many are the maximum surface area and the minimum surface area?

The maximum surface area is six in a row
The surface area is 6 * 6-5 * 2 = 36-10 = 26 square centimeters
The smallest is a 2 * 3 cuboid
Surface area = 6 * 6-7 * 2 = 36-14 = 22 cm2

Put 64 small cubes whose edges are all 1cm into a big cube. What is the surface area of the big cube

64 = 4x4x4, so there are 4x4 = 16 squares with 1cm sides on each face, and there are 6 faces in total, so the surface area is 96cm ^ 2

A pile of building blocks is made of small cubes with 16 fast edges and a length of 1cm. How many square centimeters is its surface area?

4 * 4 = 16 square centimeters
16 * 2 = 32 square centimeter
1 * 4 * 4 + 32 = 48 square centimeter

The edge length is 1 decimeter cube, and its surface area is () square decimeter. Use three such cubes to form a cuboid, and its surface area is () square centimeter
centimeter

A cube with an edge length of 1 decimeter has a surface area of (6) square decimeters. Three such cubes are used to form a cuboid with a surface area of (14) square centimeters
