A rectangular iron plate weighs 468 kg. It is 2 meters long, 1.5 meters wide and 2 cm thick. How many kg does each cubic decimeter iron plate weigh? (set up equations and formula solutions) well, we have to figure out
There's another one
Two identical cuboids, 6 cm in length, 5 cm in width and 3 cm in height, are used to form a cuboid with the smallest surface area. What is the surface area and volume of the cuboid~

1. Take a look at the number of people in the 468 kg iron plate, 1 cubic decimeter, 468 / (2x10x1.5x10x2 / 10) = 468 / 60 = 7.8 (kg / cubic decimeter) 2. The volume after assembly remains unchanged, which is the sum of the volume of the original two cuboids

A cuboid plate weighs 468 kg. It is known that the plate is 2 meters long, 1.5 meters wide and 0.02 meters thick. How many kg does it weigh per cubic meter of iron plate

[interpretation]
Plate volume = length × width × thickness = 2 × 1.5 × 0.02 = 0.06 (M3)
Weight per cubic meter = plate weight ／ plate volume = 468 ／ 0.06 = 7800 (kg)
[answer] each cubic meter of iron plate weighs 7800 kg
