How do i find surface area of a prism?

Step-by-step explanation:

If you want the surface area of a rectangular prism, then you'll use a formula resembling this:

A = 2(area of end) + 2(area of top) + 2 (area of side).

Example:  suppose the dimensions of the prism are 3 in by 5 in by 8 in.

Then the total surface area is:

A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or

A = 30 + 96 + 80 sq in, or A = 206 sq in

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
