Answer:
the length of base and height of shed are 9 cm and 18 cm respectively.
Step-by-step explanation:
let the length of the base be = x ft ( the base is square)
and height be = y ft
given volume o the shed = 1458 cm^3
⇒
also, according to question total cost C
now put y= 1428/x^2 in the above equation
now differentiating we get
now set it equal to zero for most economical cost
on calculating we get x= 9 cm
and y= 18 cm
therefore, the length of base and height of shed are 9 cm and 18 cm respectively.
