A metal sheet made up the faces of a cube measured 12 cm x 12 cm x 12 cm. find the total area of metal sheet required
A cube has six sides, each 12x12 cm^2
12X12X6=864cm
To find the total area of the metal sheet required to make the faces of the cube, you need to calculate the area of each face and then find the sum of all the areas.
A cube has six identical square faces. In this case, each face measures 12 cm x 12 cm.
To find the area of one face, you multiply the length and width:
12 cm x 12 cm = 144 cm^2
Since each face has an area of 144 cm^2, and there are six faces in total, you multiply the area of one face by six to get the total area of all the faces:
144 cm^2 x 6 = 864 cm^2
Therefore, the total area of the metal sheet required to make the faces of the cube is 864 cm^2.
