18 sq m = 193.75 sq ft = 27900 sq in

at 1 inch deep = 27900 cu in = 16.15 cu ft

sand weighs 100 lbs/cu ft

You need 100 x 16.15 = 1615 pounds or 16.15 cu ft = 0.6 yards

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the volume of a room 8 meters wide and 5 meters long and 4 meters high?

160 square meters.


What is the square meter if a wall is 9 meters long x 2 meters high?

18 meters (length x height).


The area of four walls in a room is 120msquare the length is twice its breadth its height is 4mwhat is the area of the floor?

Think of the room as a box with four sides and a bottom. You want to know the area of the bottom. You know that the total area of all four sides added together is 120 square meters. You don't know the dimensions of each wall yet, but you know the ratio: length is twice the breadth or width. You know that the height of each side is 4 meters. So use those values to assign variables to the length and width of each side. Each set of opposite sides will be equal in area. Say there are four sides: A, B, C and D. Sides A and C are opposite each other; sides B and D are opposite each other. Say sides A and C are the longer sides. That means that sides A and C are each 2x meters long and 4 meters high. The area of each side is 8x square meters. Sides B and D are the shorter sides. They are each x meters long and 4 meters high. The area of each side is 4x square meters. Now you have an expression for the area of each of the four sides. Set their sum equal to 120 square meters and solve for x. 8x + 8x + 4x + 4x = 120 24x = 120 x = 5 So x = 5. That tells you that the length of sides A and C is 2(5) = 10 meters each, and the length of sides B and D is 5 meters each. That gives you the information to solve for the area of the bottom of the box, or the floor. Just multiply the lengths: 5 x 10 = 50 square meters. The floor of the room is 50 square meters. Two of the walls are 10 x 4 or 40 square meters each, and two of them are 5 x 4 or 20 square meters each. Altogether the four walls are 40 + 40 + 20 + 20 = 120 square meters. Drawing a diagram in these kinds of problems really helps!


How many meters of fencing wiil be needed if a fence was built around a 44 by 48 meter lot?

Assuming the lot is square, you will need to find the perimeter of the lot. The perimeter is equal to the sum of the length of every side of the figure. In this case, (again, assumed), the figure is a square. This square has two sides of length 44 meters and two sides of length 48 meters. The calculation would be as follows:(44 + 44 + 48 +48) = 184 meters of fencing.If you also needed to find the number of square meters of fencing actually needed to build the fence, you could then multiply 184 (the total length of the perimeter you intend to enclose) by the desired height of the finished fence. Say you wanted a 2-meter-high fence.You could then calculate:184 meters long x 2 meters high = 368 meters^2, or 368 square meters of fencing.


If a wall is 2300 mm high and 7000 mm long how many square meters is there?

Height = 2300mm = 2.3m, Length = 7000mm = 7m Area = Length * Height = 2.3*7 = 16.1 sq m

A column of liquid is 3.62 meters high and the area of its base is 12.34 square meters What is the volume of the column?

The formula for volume is equal to the area of the base times the height. The answer will be in cubic meters. It would be 3.62 times 12.34 which equals 44.67 cubic meters.


What is the square meters of a dwelling that is 4 meters wide 5 meters long and 2.5 meters high?

If the width is 4 meters and the length is 5 meters, then the floor is 20 square meters. If you meant the volume of the room in cubic meters, then you multiply the area of the floor, 20, by the height, 2.5. The answer is 50 cubic meters.


How do you work out square meters in a roof 5 meters x 5.5 meters roof is 1.5 meters high from block work?
