1 Bag = 1.25 Cft 2.65/1.25 = 2.12 Bags
Sand: ¾ x 10.58 = 7.93 Cft.
Tiles
Qs: Find the Quantity Of Tiles If Length of Roof = 20 Ft & Width = 15 Ft ?
Sol: First Find The Volume Of Tile Volume = L x B x H
Volume Of Tile; L = 1 Ft , B = 6 inch or 0.5 Ft
1 x 0.5 = 0.5
Now Divide The Sum of area of the Roof With the Tile volume.
Total Area of Roof = 20 x 15 = 300 Sft
Volume of one Tile = 0.5 SqFt
300/0.5 = 600 Tiles
Or: 20 x 15 = 300 300 x 2 = 600 Tiles
Because In Every Row One Tile Adjusted So The Number Of Rows Are 2 So We Multiply it with 2.
Bricks
Qs:Toi Find The Brick in a Room L = 20 Ft, B = 15 Ft, Thickness Of Wall = 0.75 Ft
Height = 10 Ft ?
Sol: In Room We Have 2 Long Walls & 2 Short Wall So We Will Cut Of Two Short
Walls Or Two Long Walls Width To find Actual Quantity.
20 + 0.75 + 0.75 = 21.5 Ft

Cell No : 0341-7549889
Long Wall: No x L x BThickness
x H = Quantity
Long Wall = 2 x 21.5 x 0.75 x 10 = 322.5 Cft
Short Wall = No x L x B Or Thickness x H = Quantity
Short Wall = 2 x 15 x 0.75 x 10 = 225 Cft
Volume of 1 Brick = 0.0703
Now add Long wall & Short Wall
322.5 + 225 = 547.5 547.5/0.0703 = 7788 or 7800 Bricks
Or 547.5 x 14.2 = 7774.5 or 7800 Bricks

Find The Weight?
Sol: L = 10 , D = 1 inch 1 inch = 8 Sutar so 1 x 8 = 8 Sutar
W = D2
/24 x L W = (8)2
/24 x 10 = 6400/24 = 266.66 Lbs.
Lbs. is the unit of pound so change it to kg 1kg = 2.204 Lbs.
266.66/2.204 = 120.98 kg.

QS: A Steel Bar Having Length = 80 m Dia = 6 cm Find Weight?
Sol: in Meter System Dia must Be in millimeter.
1 cm = 10 mm 6 x 10 = 60 mm
W = D2
/162.162 x L = (60)2
/162.162 x 80 = 288000/162.162 = 1776 kg
W = 1776 kg Conver it to Ton Divide it on 1000
1776/1000 = 1.776 Ton.

Qs: Core Cutter Was Used to Determined Density for a Road
Site. Weight of the Cutter was 1286 Gram & Total Weight Was
3195 gram. Volume of Core Cutter was 1000 cm3
& Water Content
Was 12%. Determine Bulk Density of This Sample?
Sol: Net of soil in Core Cutter:
W = 3195 – 1286 = 1909 gram
Volume of Core Cutter = V = 1000 c.c
Bulk Density = W/V = 1909/1000 = 1.909 Gm/c.c
M = 12% = 12 x 100 = 0.12
Bulk Density = ϓ/1 + m
Symbol of Bulk Density = ϓ
Bulk Density = 1.909/1 + 0.12 = 1.909/1.12
