Answer:
1)2(lb+bh+hl)
=2(17*12+12*8+8*17)
=2(204+96+136)
=2*436
=872 in^2
2)2*pi*r(r+h)
=2*3.14*14(14+29)
=6.28*14(43)
=6.28*14*43
=3780.56 mm^2
3)A=11*4.3+3*6 +3*8+11*3(Area of each plane figure -triangle and rectangle)
=47.3+18+24+33
=122.3cm^3
4)h*(sum of II sides)+14*8+19*8+14*8+25(Area of plane surface-trapezium,rectangle,square)
=12.1(19+5)+112+152+112+25
=12.1*24+401
=290.4+401
=691.4ft^2

Step-by-step explanation:
Answer:
a ^ (1/12)
Step-by-step explanation:
a ^ (1/3)
---------------
a ^ (1/4)
We know that b^ c / b^ d = b ^ (c-d)
a^ (1/3 - 1/4)
getting a common denominator
1/3 *4/4 - 1/4*3/3 = 4/12 - 3/12
a^ (4/12 - 3/12)
a ^ (1/12)
