Question

surface areas and curved surface areas all formulaes​

Answer 1

Answer:

$\huge\underline\mathfrak\red{❥Answer}$

Step-by-step explanation:

Shape Latera Surface Area (LSA) Total Surface Area (TSA)

Cuboid 2h(l + b) 2(lb + bh + lh)

Cube 4a2 6a2

Right Prism Base perimeter × Height LSA + 2 (area of one end)

Right Circular Cylinder 2πrh 2πr(r + h)

Right Pyramid (1/2) Perimeter of base × Slant Height LSA + Area of Base

Right Circular Cone πrl πr(l + r)

Solid Sphere 4πr2 4πr2

Hemisphere ½ × 4 × πr2 3πr2

Answer 2

Answer:

1. Lateral surface area of cuboid (LSA)=2h(l+b)
2. Lateral surface area of cube (LSA)=

${4a}^{2}$

1. Total surface area of cuboid(TSA)=2(lb+bh+lh)
2. Total surface area of cube (TSA)=

${6a}^{2}$

1. Total surface area of cylinder (TSA)=

$2 \times \pi \times r \times \: r + h$

1. Total surface area of cone (TSA) =
2. $\pi \times r \times r + l$
3. Total surface area of hemisphere (TSA)=
4. $3\pi \times {r}^{2}$
5. surface area of sphere (TSA)=
6. $4\pi \times {r}^{2}$
7. Curved surface area of cylinder (CSA)=
8. $2\pi \times r \times h$
9. Curved surface area of cone (CSA)=
10. $\pi \times r \times l$
11. Curved surface area of hemisphere (CSA) =
12. $2\pi {r}^{2}$
