Can anyone do this for me plz :))

You can calculate this yourself via:

Volume = Length*Width*Height

Height = Volume / (Length*Width)

Area = Length*Width*2 + Length*Height*2 + Width*Height*2

Step-by-step explanation:

c) l = 10 cm

   w = 8 cm

Volume = 400 cm^3

l*w*h= 400

10 * 8 *h = 400

h= 5 cm

Surface area = 2*(lw + wh + lh)

 = 2*(10*8 + 8*5 + 5*10)

= 2*(80 +40 +50)

=2*170

= 340 cm²

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
