Find the surface area of a cubic open tank side 7m?

The surface area of a cubic open tank can be calculated by finding the area of each of the six sides and adding them together.

Since all sides of a cube are equal, the area of each side is given by the formula:

Area = side^2

Given that the side of the tank is 7m, the area of each side is:

Area = 7^2 = 49 square meters

Since there are six sides in a cube, the total surface area of the tank is:

Total surface area = 6 * 49 = 294 square meters

Therefore, the surface area of the cubic open tank with a side length of 7m is 294 square meters.

The surface area of an open cubic tank with a side of 7m is given by:

Surface Area = 5 × Side²
Surface Area = 5 × 7²
Surface Area = 5 × 49
Surface Area = 245 m²

Therefore, the surface area of the cubic open tank is 245 square meters.
