The edge length of a cube is 5cm, and four such cubes are used to form a large cuboid. The surface area of a large cuboid may be () square centimeter or () square centimeter The edge length of a cube is 5cm. Four cubes are used to form a large cuboid. The surface area of a large cuboid may be () square centimeter or () square centimeter

The edge length of a cube is 5cm, and four such cubes are used to form a large cuboid. The surface area of a large cuboid may be () square centimeter or () square centimeter The edge length of a cube is 5cm. Four cubes are used to form a large cuboid. The surface area of a large cuboid may be () square centimeter or () square centimeter


The surface area of a large cuboid may be (400) square centimeters or (450) square centimeters
10 * 10 * 2 + 5 * 10 * 4 = 400 (square centimeter)
5 * 20 * 4 + 5 * 5 * 2 = 450 (cm2)



Two cuboids with 5cm edges are put together to form a cuboid. How much is the surface area of the cuboid reduced?


I know



A cuboid is made up of five cuboids whose edges are 1cm long, 5cm long, 1cm wide and 1cm high
This is a judgment question.


I didn't make it clear. There are several other ways
It can only be said that this method is one of them
If it's a judgment, it's wrong



A cuboid with 5cm long, 4cm wide and 3cm high can be made up of () small cubes with 1cm long edges


The volume should be the same
5*4*3/1^3=60cm
A: 60 cubes are needed
Don't know how to ask me on hi



Xiao Ming uses five square building blocks with 2cm long edges to form a "ten" (as shown in the picture). What is the surface area of the "ten"?


2 × 2 × 5 × 4 + 2 × 2 × 2 = 88



There are cube blocks with edge length of 5cm. If you put these four blocks together, what is the maximum surface area? What is the minimum surface area?


The maximum should be that there are no more than one stacked on each other, for example, four stacked into a high body, so that the surface area is 4 * 6 * 25-6 * 25 = 450 square centimeters;
The minimum is four piles, with a surface area of 12 * 25 = 300 square centimeters



The surface area of cuboid building block is n square centimeter. It can be sawed into two cube building blocks. After sawing, the surface area of each cube building block is () flat


The surface area of cuboid block is n square centimeter. It can be sawed into two cube blocks. After sawing, the surface area of each cube block is (0.6N) square centimeter
N÷10×6 = 3N/5 =0.6N



How many square centimeters is the minimum surface area of the cuboid?


Two answers: first, in a row (5 * 20 * 4 + 25 * 2 = 450); second, in a row of two (5 * 10 * 4 + 10 * 10 * 2 = 400)



Using eight square blocks with one centimeter long edges, you can make a variety of cuboids, of which the smallest surface area is several square centimeters


1 × 1 × 8 surface area = 2 + 4 × 8 = 34 (cm2)
1 × 2 × 4 surface area = 2 × (1 × 2 + 2 × 4 + 1 × 4) = 28 (square centimeter)
2 × 2 × 2 surface area = 4 × 6 = 24 (cm2)
There are three different kinds of cuboids, the smallest of which is 24 square centimeters



How much is the surface area of a cuboid made of three square building blocks with one centimeter long edges?


3×1×4+1×1×2=14
