Respuesta :
Cube has all six faces as square. The surface area of the outside of one of the bins is 13.5 m².
What is the surface area of the cube?
The surface area of the cube is the sum of the area of all the sides of the cube. All the six sides of the cube are made of the same size square, therefore, the surface area of the cube is 6s², where s is the length of its single side.
As it is given that the melons are kept in cubic bins whose top is closed, therefore, the cubic bin will have all six sides, with the length of the side as 1.5m.
We know the formula for the surface area of the cube, therefore, the surface area of the cubic bin is equal to the surface area of the cube with side 1.5m,
[tex]\text{Surface area of the cube} = 6s^2[/tex]
[tex]= 6(1.5)^2\\\\= 6 \times 2.25\\\\=13.5\rm\ m^2[/tex]
Hence, the surface area of the outside of one of the bins is 13.5 m².
