Answer:
3060
Step-by-step explanation:
<u>Find the cross-sectional area first of the trapezium</u>
So,
which is 40 / 2 x 15 = 20 x 15 = 300
Since there are 2 trapeziums (on the front and back): 300 x 2 = 600
<u>Find the Area of the Rectangles</u>
The first rectangle on the top would be: 6x30 = 180
The slanted rectangle on the right would be: 25x30 = 750
The rectangle on the bottom would be: 30x34 = 1020
The hidden rectangle on the left would be: 17 x 30 = 510
So by combining all these calculations, you will get the total surface area which is:
600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060
2.295 that’s what I think! :)
