After the 2-meter-long square wood was sawed into 4 equal parts, the surface area increased by 24 square decimeters. What is the volume of the original square with a root?
A 2-meter-long square wood is sawed into 4 sections, and it needs to be sawed 3 times, and each saw adds 2 faces, so a * * * adds 2*3=6 faces.
The area of each part is 24/6=4 square decimeters.
Square timber volume V = S (cross-sectional area) * H (height)
