80 pieces of cuboid wood are piled into a cuboid with a length of 4m, a width of 8m and a height of 5m. What is the average volume of each cuboid wood? How much is it April 3, 2013 21:56:12

80 pieces of cuboid wood are piled into a cuboid with a length of 4m, a width of 8m and a height of 5m. What is the average volume of each cuboid wood? How much is it April 3, 2013 21:56:12

4×8×5÷80
= 160 ÷80
=2 M3

A cuboid wood, 5m long, has a cross-sectional area of 0.06m & sup2?

A cuboid wood, 5m long, with a cross-sectional area of 0.06m & sup2. What is the volume of this wood?
According to the area of cuboid = bottom area × length
And cross section = bottom area
The volume of this wood is: 0.06 × 5 = 0.3 (M3)
A: the volume of this wood is 0.3 cubic meters

A cuboid wood, 4m long, with a cross section of 0.08 square meters, how many cubic meters is the total volume of this pile of wood?
To list
Can't different units be added or subtracted?

0.08 × 4 = 0.32 (M & sup3;) cuboid volume = length × width × height v = ABH ⁃ cuboid (or cube) volume = bottom area × height v = sh, because length × width is equal to cuboid bottom area, and then × height is volume, which is equivalent to length × width × height
