Question

The formula a = 6s^2 can be used to find the surface area of a cube, where s represents the side length of the cube. What is the surface area of a cube with a side length of 3/4 of a meter?

a) 9/2 square meters

b) 27/4 square meters

c) 27/2 square meters

d) 81/4 square meters

Answer 1

The surface area of a cube with a side length of 3/4 of a meter is 27/8 square meters.

Step-by-step explanation:

To find the surface area of a cube with a side length of 3/4 of a meter, we can use the formula a = 6s^2, where a is the surface area and s is the side length of the cube. Plugging in the value of s as 3/4, we get a = 6(3/4)^2. Simplifying this equation, we have a = 6(9/16) = 54/16 = 27/8. Therefore, the surface area of the cube is 27/8 square meters.
