18x20x2 + 15x20x2 = 1320 (square centimeter),
Hope to adopt!

If three cubes with surface area of 24, 54 and 294 square centimeters are fused into a large cube (excluding loss), how many cubic centimeters is the volume of the large cube

24 △ 6 = 4 (square centimeter), because: 2 × 2 = 4, so: edge length is 2cm; 54 △ 6 = 9 (square centimeter), because: 3 × 3 = 9, so: edge length is 3cm; 294 △ 6 = 47 (square centimeter), because: 7 × 7 = 49, so: edge length is 7cm; large cube volume: 2 × 2 × 2 + 3 × 3 + 7 × 7 = 8 + 27 + 343 = 378 (cubic centimeter); answer: the volume of this large cube is 378 Square centimeter

When the height of a cuboid is increased by 3cm, it becomes a cube. The surface area is increased by 96 square cm. What is the volume of the cuboid?

The bottom is a square. Let the side length of the bottom be X
4×3X=96
X=8
Then the original height = 5
V = 8 × 8 × 5 = 320 square centimeter

Three cubes with surface areas of 54, 96 and 150 cm2 are fused and cast into large cubes. Regardless of loss, what is the surface area of large cubes?

"Ningyun ice cloud": square with surface area of 54, 96 and 150 square centimeters, and their side lengths are 3, 4 and 5 cm respectively. The total volume of the three squares is: (3 & # 179; + 4 & # 179; + 5 & # 179;) cubic centimeter = (27 + 64 + 125) cubic centimeter = 216 cubic centimeter. The side length of the large square is 6 cm (3 times)

If the height of a cuboid is increased by 2cm, it becomes a cube, and the surface area is increased by 56cm
What's the volume of the cuboid?

Perimeter of the bottom of the cuboid:
56 △ 2 = 28 (CM)
Side length of the bottom of the cuboid:
28 △ 4 = 7 (CM)
Height of cuboid:
7-2 = 5 (CM)
Volume of the cuboid:
7 × 7 × 5 = 245 (cm3)

For a cuboid, the height increases by 2cm, the length and width remain unchanged, the surface area increases by 56cm2, and the cuboid becomes a cube. How many cubic centimeters is the volume of the cube?
It's urgent. Right now

From cuboids to cubes, we can see that cuboids have the same length and width. Let a be a,
Then a × 2 × 4 = 56;
A = 7cm, i.e. 7cm in length and width
Cube volume 7 × 7 × 7 = 343cm2

If the height of a cuboid is increased by 2cm, it becomes a cube, and the surface area is increased by 56cm & sup2;. The cuboid volume is calculated
Please solve it by arithmetic

56/2/4=7 7*7*5=245

A cuboid, 5 cm longer, becomes a cube, and its surface area increases by 160 square cm. What is the volume of this cuboid______ Cubic centimeter

The width and height of the original cuboid are: 160 ／ 4 ／ 5 = 8 (CM), the length of the original cuboid is: 8-5 = (CM), 3 × 8 × 8 = 192 (cm3), answer: the volume of the original cuboid is 192 cm3. So the answer is: 192

A cuboid becomes a cube when its width increases by 5 cm. At this time, its surface area increases by 160 square cm. What is the volume of this cuboid

The side length of the square is: 160 △ 4 △ 5 = 8 (CM)
The volume of a rectangle is: 8 × (8-5) × 8 = 192 (cubic centimeter)

A cuboid, 5 cm longer, becomes a cube, the surface area increased by 160 square centimeters, the cuboid volume
What does each number represent?

What is the circumference of the cross section of a cuboid
160 △ 5 = 32 cm
What is the length and height of a cuboid
32 △ 4 = 8 cm
What is the width of a cuboid
8-5 = 3cm
What is the volume of a cuboid
8 × 8 × 3 = 192 CC
