If the length of a cube is 6 inches, what is the surface area?

Step-by-step explanation:

We can find the surface area of an object by finding the area of all its sides and adding them up.

We know that a cube has 6 identical sides. Therefore, we can just find one side and multiply by 6.

A cube is made up of 6 squares. We can find the area of this square by squaring the length (multiplying it by itself).

Since the length is 6, that means the area of one side of the cube must be

Since there are 6 identical sides, the total surface area must be:

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
