A rectangular storage container with an open top is to have a volume of 10 cubic meters. The length of its base is twice the wid

drek231 [11]

Answer:163.54$

Step-by-step explanation:

Given data

Volume of Storage(V)= ${10m^3}$

Length=2breadth

Let Length be L,Breadth be & height be H

therefore

10=LBH

Now substitutes the values

10=2 ${B^2}H$

5= ${B^2}H$

Now cost for base is ${C_1}=2{B^2}\times10$

Cost for side walls is ${C_2}={2LH}\times6+2BH}\times6$

Now total cost(C)= ${C_1}+{C_2}$

C=20 ${B^2}H$ + ${2LH}\times6$ + $2BH}\times6$

C=20 ${B^2}H$ +24BH+ $12BH$

C= $20{B^2}+36B\times\frac{5}{B^{2}}$

Now Differentiating With respect to Breadth to get minimum cost

$\frac{\mathrm{d} C}{\mathrm{d} B}=0$

$we\ get\ B=\sqrt[3]{4.5}=1.65m$

$L=3.30m$

$H=1.836m$

and mimimum cost C

${C=163.54\$}$

agasfer [191]

Answer:

Step-by-step explanation:

0.4 × 3.2

Convert to fraction

0.4 = 4/10 = 2/5 & 3.2 = 32/10 = 16/5

0.4 × 3.2 = 2/5 × 16/5 = 32/25 = 1.28

Without conversion you press ur calculator and you get 1.28
