Answer 2

Answer:

The total surface area of cube is 150$cm^2$.

Step-by-step explanation:

Step 1:The cuboid has six rectangular sides, hence the following formula is used to get its total surface area: Assume that the cuboid's length, breadth, and height are, respectively, l, w, and h. As a result, the cuboid has a total surface area of 2 (lh + lw + hw) square units.

Step 2:A cube is a three-dimensional solid object in geometry that is surrounded by six square faces, facets, or sides, three of which meet at each vertex. It looks like a hexagon when viewed from a corner, and its net is typically shown as a cross. One of the five Platonic solids, the cube is the only regular hexahedron.

Step 3: Given, the side of a cube is$5 \mathrm{~cm}$.

Step 4:Total surface area of cube $=6 \times(\text { side })^2$

$=6 \times 5 \times 5$

=150

The total surface area of cube is $150 \mathrm{~cm}^2$.
