For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 1,400 square feet. Divide by 9 to get 155.56 square yards.
If the room is a rectangle then the area is 13 times 40 = 520 square ft.
There is no way to compute the dimension of a rectangle from its area. 40 square inches, you see, could be 1"x40" or 2"x20", or 4"x10", or . . . . . . but they would all be 40 square inches.
20 feet times 40 feet = 800 square feet
Area is two dimensions. You've given four, defining a hypervolume of 70x40x60x30 = 5,040,000 ft4 (hypercubic feet). If you mean TWO areas, it's just a matter of simple multiplication, which is left as an exercise for the student: 70x40 = ___ ft2 (sq.ft., square feet) 60x30 = ___ ft2 (sq.ft., square feet)
Yards are for measuring length not volume. Cubic yards required will be as follows: 1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet 400 divided by 27 = 14.8148 cubic yards required

To find the square footage of a rectangle, you multiply the length by the width. In this case, 30 feet multiplied by 40 feet equals 1200 square feet. Therefore, there are 1200 square feet in a 30'x40' area.
17.3 cubic yards will do it.
5'3''x40'x3' = 52.5 cubic feet = 1.94 cubic yards. I'd order 2.5 to be safe.

14.81 cubic yards.
For area measurements, you multiply the length by the width. Here the calculation gives you an answer of 1,200 square feet.
A 40'x40'x6" slab requires 29.63 cubic yards of cement.
About 24 cubic yards of cement is required for a slab that size.
30" x 40" = 1,200 square inches.
