Question

What is the surface area of the figure above 4 cm and height 8 cm in length 5 cm in width a 50 cm square b 192 cm square c 160 cm square d 184 cm square

Answer 1

To find the surface area of the figure, we need to find the area of each of its faces, and then add them up.

The figure is a rectangular prism, which has 6 faces:

1. Top and bottom faces: 5 cm * 4 cm = 20 cm² each
2. Front and back faces: 5 cm * 8 cm = 40 cm² each
3. Left and right faces: 4 cm * 8 cm = 32 cm² each

Adding up all the areas, we get:

20 cm² + 20 cm² + 40 cm² + 40 cm² + 32 cm² + 32 cm² = 184 cm²

Therefore, the surface area of the figure is 184 cm².

So, the answer is d) 184 cm square.
