What is the total surface area of the figure?
___ mm2

Answer 1

Wrong

Answer 2

The total surface area of the figure can be calculated by finding the area of each face and adding them all together.

1. There are 2 faces that are 10 mm x 2 mm = 20 mm2 each.
2. There are 2 faces that are 6 mm x 8 mm = 48 mm2 each.
3. There are 2 faces that are 16 mm x 8 mm = 128 mm2 each.

Adding all the areas together:
(20 mm2 x 2) + (48 mm2 x 2) + (128 mm2 x 2) = 40 mm2 + 96 mm2 + 256 mm2 = 392 mm2

Therefore, the total surface area of the figure is 392 mm2.

Answer 3

I apologize for the mistake. Let's try calculating the total surface area of the figure again.

Given dimensions:
1. 2 faces with dimensions 10 mm x 2 mm = 20 mm2 each
2. 2 faces with dimensions 6 mm x 8 mm = 48 mm2 each
3. 2 faces with dimensions 8 mm x 16 mm = 128 mm2 each

Calculating the total surface area:
2 * (20 mm2) + 2 * (48 mm2) + 2 * (128 mm2)
= 40 mm2 + 96 mm2 + 256 mm2
= 392 mm2

Therefore, the correct total surface area of the figure is 392 mm2.
