Answer 1

Answer:

1. find the Total surface area and Lateral surface area of a cuboid with length = 3.5m breadth = 32dm and height = 260cm. Please solve this problem. The answer of the question is TSA = 348.4, LSA = 348.4.
2. a=20
3. A Surface area
4. 2400
5. Lateral surface area of cube = 4 × (l) square units. = 4 × 12cm × 12cm = 4 × 144cm = 576cmsquare.
6. Lateral surface area of a cube = 4 (side)2. Total surface area of a cube = 6 (side)2. Lateral surface area of a cuboid = 2 × height × (length + breadth). Total surface area of a cuboid = 2(lb + bh + hl).
7. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
8. AL≈2463.01cm²
9. r Radius
10. 14
11. cm
12. h Height
13. 28
14. cm
