Question

an someone please help me with this math homework please am in 7th grade https://ibb.co/nBwvLJT and https://ibb.co/5n9MYDr

Answer 1

we want the lateral surface area and the total surface area

so once more, lateral surface area is just the area without the bases so without the triangles

Answer 2

ok

Answer 3

so the green rectangles

the width is 1 cm but the lengths are 2.5, 3 and 2.5

so the big green rectangle has a width of 1 and a length of (2.5+2.5 + 3) = 8

so what is the area of a rectangle with width 1 and length of 8

Answer 4

8

Answer 5

Yup! And if you're wondering how I got that length of 8, it's because I made the three rectangles into one big rectangle

Answer 6

oh k

Answer 7

So 8 is our lateral surface area

now to find the total surface area, we need to also find the area of the triangles

the base is 3 and the height is 2

area of triangle = 1/2 * base * height

what is the area?

Answer 8

3

Answer 9

Good! So that's the area of one triangle but we have TWO triangles

and the area of all three rectangles is 8

total surface area = 3 + 3 + 8

total surface area = ??

Answer 10

14

Answer 11

and that's your total surface area :)
