Just multiply 5m x 7m. The depth won't change the area of the top surface. Now, if you have a block and want to have its total surface area, calculate the area of the six bounding rectangles, and add them: two times 5x7, two times 5x1.6, two times 7x1.6.
5m x 5m = 25m2 (25 square metres)
5*3 = 15 square meters
More information is needed in order to answer this question. The size of the pond, preferably in square meters.
25 square meters
5m means man material many machinery maintenance
5m x 5m = 25m2 (25 square metres)
5*3 = 15 square meters
5m deep
More information is needed in order to answer this question. The size of the pond, preferably in square meters.
The answer is 20m
30 square meters
25 square meters
It is 3-5m deep
5m means man material many machinery maintenance
The area of a rectangle measuring 9m x 5m is 45 square meters.
5m * 20m = 100 m2 = 1076.4 sq ft (approx)
5m = 5000 mm.
