First the tile. The tile is 12"by 12" or 1 foot square each tile.
Floor is 10 foot by 15 foot. 10' times 15' = 150 square foot of floor.
each tile 1 foot square 150/1 = 150 tiles. ANSWER FOR TILES

Paint: four walls and one ceiling.
Ceiling is same size as floor: 150 square foot (10 times 15).
Walls: two are 10 feet long by 12 feet high.
2 (10' times 12') = 2(120 sq. foot) = 240 square foot of walls
two other walls are 15 feet long by 12 feet high
2(15' times 12') = 2(180 sq.ft.) = 360 square foot of walls.
TOTAL WALL & CEILING SQUARE FOOTAGE:
360 + 240 + 150 = 750 SQ.FT.
PAINT covers 150 sq. ft/gallon. 750/150 = 5 gallons.
PAINT algebra formula: x = cans of paint needed.
(10*15) + 2(10*12) + 2(10*15) = 150x
150 + 2(120) + 2(180) = 150x
150 + 240 + 360 = 150x
750 = 150x
divide each side by 150> 750/150 = 150x/150
5 = x
5 cans of paint. ANSWER FOR PAINT.

Using Quincy, write a C program that will ask the user for 4 integer values and then produce the following out?

Please someone help..??! Python Programming Help?

We Answered:

User will input an area, and you have to determine how high you grain would pile in that area.

You know the mass of the wheat (from problem B) and the density of the wheat (given).

So you can use that to determine the volume of the wheat.

Volume is area * height. So to find height you'll need to do Volume / Area

Height = Volume / Area = (mass / density) / area

Remember, grams (and mg) measure mass. It's common to substitute that for weight in metric.

Help with a Math word problem. Help! Please!!?

Dimensions of room :
length = 10 ft
width = 15 ft
height = 12 ft

Now each tile she chose is 12"X12" per tile. = 1 ft *1ft

The area of the floor = length * width = 10*15 sq ft
= 150 sq ft

So each tile has area of 1 ft*1ft = 1sqft
So the number oftiles to cover 150 sq ft area of the floor = 150/1 = 150 tiles
NOw the paint is covering the 4 walls plus ceiling
So surface area covered is
= area ofthe 2 longer walls + area of the 2 smaller walls + ceiling area
=2 ( length* height) + 2 (height* width) + (length* width)
2 (10*12) + 2 ( 12*15) + 10*15
2 (120) + 2(180) +150
240 + 360 + 150
750 sqft

So 1 gallon of paint will cover 150 ft squared
So X gallons covers 750 sq ft
X = 750*1/ 150 = 5 gallons


So tiles requires are 150
And 5 gallons paint required
