Can someone me work out the surface area

Step-by-step explanation:

Let A be the surface area of the triangular prism

Given:

A triangular prism

Height

Base

Perimeter of the base triangle (p = 6 + 8 + 10 = 24 cm)

Now we calculate the surface area of the triangular prism.

Solution:

We know that the surface area of the triangular prism.

-------------(1)

First We calculate the lateral surface area of the triangular prism.

Perimeter of the base and height are known, so we substitute these value in above equation.

Therefore the lateral surface area of the triangular prism

Now we calculate area of the base.

Where b = base and h = Height are known.

So the area of the base

Substitute Lateral surface area and base area in equation 1.

Therefore the surface area of the triangular prism

over the argument its not good to fight.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
