The shape below is a cute with the length of 13cm. find the total surface area of the prism

The area is 1,014 cm^2

Step-by-step explanation:

Here, we want to find the total surface area of a cube with side length of 13 cm

what we shall do here is to apply the formula to get the total surface area

Mathematically, that will be

A = 6L^2

so we have

Area = 6 * 13^2

Area = 1,014 square cm

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
