Answer:

150 m.

Step-by-step explanation:

SA= 6xa²

A cube has six sides so you factor that in. What you do is square the length of one of the sides and then multiply by how many sides there are.

5^2=25

25x6=150.

The surface area of the cube above is 150 m²

Further Explanation

Area

  • Area is a measure of how much space is occupied by a given shape.
  • Area of a substance is determined by the type of shape in question.

For example;

  • Area of a rectangle is given by; Length multiplied by width
  • Area of a triangle = 1/2 x base x height
  • Area of a square = S², Where s is the side of the square.etc.

Surface area

  • Surface area is the sum of the areas of all surfaces or faces on a three dimension shape such as cuboid, cube, cylinder, prism, etc.

Surface area of a cube

  • A cube has six sides so you factor that in. Thus, to get surface area we square the length of one of the sides and then multiply by how many sides there are.
  • Hence surface area of a cube = 6S², where S is the length of the cube.

In this case,

S = 5 m

Therefore, surface area = 6 × 5²

                                        = 6 × 25

                                       = 150 m²

Therefore; the surface area of the cube above is 150 m²
