You can calculate this yourself via:
Volume = Length*Width*Height
Height = Volume / (Length*Width)
Area = Length*Width*2 + Length*Height*2 + Width*Height*2
Answer:
Step-by-step explanation:
c) l = 10 cm
w = 8 cm
Volume = 400 cm^3
l*w*h= 400
10 * 8 *h = 400
[tex]h=\frac{400}{10*8}=5\\[/tex]
h= 5 cm
Surface area = 2*(lw + wh + lh)
= 2*(10*8 + 8*5 + 5*10)
= 2*(80 +40 +50)
=2*170
= 340 cm²
