What is the surface area of an ice cube that has 4 cm sides?

surface area of cube is 6a²

Step-by-step explanation:

6×4×4

96cm²

96 cm²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a three-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area. So we can simply find the area of one face of a cube and multiply by the number of faces, which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square which is A = s². Since the length of a side is 4 cm, we have (4 cm)² or 4 centimeters · 4 centimeters which is 16 cm².

Now, since there are six sides to a cube, we have 6 (16 cm²) which is equal to 96 cm². So the surface area of the ice cube is 96 cm².

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
