Please help me with this sheet asapb

Step-by-step explanation:

1)

SA= 2 (Length x Breadth + breadth x height + Length x height)

SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2

2)

2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2

3)

2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2

4)

SA=

= 2π 6*5+2π6*6= 188.495+226.194

SA= 414.689 cm^2

5)

2π7*4+2π*4*4=

SA=276.46 cm^2

6)

2π6*4+2π*4*4=

SA= 251.33 cm^2

7)

(3*4)/2=6

(3*4)/2=6

(3*8)=24

4*8=32

8*5=40

SA =6+6+24+32+40=108 cm^2

8)

(6*8)/2=24

(6*8)/2=24

6*12=72

8*12=96

10*12=120

SA= 24+24+72+96+120= 336 cm^2

9)

(5*12)/2=30

(5*12)/2=30

5*8=40

12*8=96

13*8=104

SA= 30+30+40+96+104= 300 cm^2
