It says find the surface area of the rectangular prism. You get 36 points!!

Step-by-step explanation:

surface area of given figure:

l= 17

b = 11

h= 14

now curved surface area =

2 (lh +bh) +lb

= 2(17 × 14 + 11 ×14 ) + 17 ×11

= 2(238 + 154) + 187

= 2×392 + 187

= 8624 + 187

= 8811 cm^2

total surface area =

2(lb + lh + bh)

2 ( 17×11 + 17 × 14 + 11 ×14)

= 8998 cm^2

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
