There is a cuboid with a square bottom, 20 cm high, and a square side. Find the volume of the cuboid
Side length of the bottom: 20 △ 4 = 5 (CM), volume: 5 × 5 × 20 = 500 (CC); answer: the volume of this cuboid is 500 cc
A cuboid, whose side is square and its side length is a. if its bottom is square, what is the volume of the cuboid?
xiexie~
The side is square and the side length is a
The height of the cuboid is a,
The bottom is square, so the side length of the bottom is 1 / 4A
Volume = (1 / 4A) * (1 / 4A) * a = 1 / 16 (the third power of a)
When a 5-meter-long cuboid wood is divided into five sections, its surface area increases by 128 square decimeters. What is the volume of this wood?
According to the analysis, 8 sections are added after sawing into 5 sections, so the bottom area of the cuboid is: 128 △ 8 = 16 (square decimeter); 5m = 50 decimeter, 16 × 50 = 800 (cubic decimeter); a: the volume of this wood is 800 cubic decimeter
