A rectangular storage container with an open top is to have a volume of 10 m3. The length of this base is twice the width. Mater
marshall27 [118]

Answer:

$ 327.08

Step-by-step explanation:

Let x = width of the container,

Then Length of the container = 2x

Let h = height of the container,

volume of the container can be calculated as length × width × height

= 2x × x × h

= 2x² h

Then we can say Volume =

= 2x² h=10

If we simplify inorder to get h

We have h= 5/x²

Then the area= (2L×h) +(2xh)

Where L is lenght

x= wish

h= height

= 2× 2x × h+ x× h

= 4x× 5/x + 2x × 5/x

Area = 30/x

Now, the area of the base = length × width

But from question, for the base costs $20 per square meter. Material for the sides costs $12 per square meter

Then the cost C(x)= 2x²× 20+30/x ×12

C(x)= 40x²+35/x²

If we differenciate wrt x we have

C(x)= 80-360/x²

If we equate C(x)=0the

80=360/x²

x= 1.651

If substitute to C(x)= 40x²+35/x²

C(x) = 40(1.651)² + 35/(1.651)²

We have cost= 327.08

What is the surface are of a rectangular prism of the length is 18cm the width 6cm and the height 3cm
Harlamova29_29 [7]

The surface area of rectangular prism is 360 square inches

<em><u>Solution:</u></em>

Given that rectangular prism of the length is 18 cm the width 6 cm and the height 3 cm

To find: Surface area of rectangular prism

<em><u>The Surface area of rectangular prism is given by formula:</u></em>

A=2(wl+hl+hw)

Where,

"l" is the length and "h" is the height and "w" is the width of prism

From given,

l = 18 cm

w = 6 cm

h = 3 cm

<em><u>Substituting the values in formula,</u></em>

A = 2((6 \times 18) + (3 \times 18) + (3 \times 6))\\\\A = 2(108+54+18)\\\\A = 2 \times 180\\\\A = 360

Thus surface area of rectangular prism is 360 square inches
