Calculating the weight of granite slabs... help

Bernice101

I hope im in the correct forum.

I am trying to calculate the weight of 2 granite slabs using the 2,600 kg/ m3 formula

the dimensions are:

Piece 1: 9.5 ft x 2.2 ft x300mm
Piece 2: 2.2 ft x 5.5 ft x 30mm

Ide be very grateful if someone could run these calculations for me

300mm ? You sure ?

Convert all to mm

9.5ft = 2895.6mm
2.2ft = 670.56mm

2.2ft = 670.56mm
5.5ft = 1676.4mm

2895.6*670.56*300 = 582,502,060.8 mm3
if the figure should be 30mm
2895.6*670.56*30 = 58,250,206.08 mm3

670.56*1676.4*30 = 33,723,803.52 mm3

Total is 91,974,009.6 mm3

this is .0919740096 m3


0.0919740096 = 2,600 = 239.132kg


If the 300mm figure is correct, then 616225864.32 mm3 = 0.61622586432 m3

0.61622586432 * 2,600 = 1,602.187 kg

So, either 239.132kg or 1,602.187kg

Actually, just realised I gave total weight.

Per slab:

Piece 1: 9.5 ft x 2.2 ft x300mm is 1514.505 kg in weight (or if that should be 30mm then 151.45 kg).

Piece 2: 2.2 ft x 5.5 ft x 30mm is 87.681 kg in weight.
