Volume = 2cm x 2 cm x 2 cm = 8 cm^(3).
The volume of a cube is calculated by multiplying the length, width, and height of the cube. In this case, all sides of the cube are 2cm. Therefore, the volume of the cube would be 2cm x 2cm x 2cm = 8 cubic centimeters.
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. Balsa, one of the least dense woods, has a density of 0.16 g/cm3 which is more than 3 times the "density" of your wood! So have you discovered a super-light wood species?

8 cm3 i hope this isn't for your homework
8 cubic centimetre
IF you knew the volume of the block and the density of the material it was made of you could calculate it mass (mass = density * volume) but it is normal to measure the mass of something using a mass balance.
Assuming this is a rectangular block, you are supposed to multiply the three numbers.
30 ( cm x cm )
30 cm3
Volume = 2cm x 2 cm x 2 cm = 8 cm^(3).
The volume is 4.19 cm3

Oh, dude, it's like you're trying to make me do math here. Alright, so the volume of a cube is just the length of one side cubed. In this case, it's 2cm x 2cm x 2cm, which equals 8 cubic centimeters. So, yeah, that's the volume of your little cube.

Let's assume the block of wood is a rectangular cuboid, i.e. it has six faces, each of which is a rectangle, and all the angles are right-angles. The volume V is given by:V = height x length x depthWe can define any of these three to the measurements quoted, but do make sure you are using the same units to measure all three. So in this case:V = 13 cm x 7.45 cm x 2.82 cm= 273.117 cm3Round that off as appropriate - two decimal places would be adequate, so this would be 273.12 cm3. The units are the cube of the units used to measure the lengths, so in this case we measure the volume in cubic centimetres (cm3), since we measured the lengths in centimetres (cm).
