Question

Larissa made a solid wooden block as shown in the diagram below. She will paint all surfaces of the block.



What will be the total painted surface area of the block?

Answer 1

you can start by computing surface are of each side

Answer 2

*area

Answer 3

Well, I tried.. For the rectangle part I got 306.

Answer 4

ok

lets compute one by one again.
surface area of bottom = 10 * 15 = 150
surface area of top = 6 * 15 = 90
surface area of right side = 3 * 15 = 45
surface area of left side = 5 * 15 = 75

thats 360 for rectangles


we still need to find areas of 1) front and 2) back

Answer 5

thats front view right

Answer 6

right..
