Answer:

273.295 m^3

Step-by-step explanation:

Well I'm going to assume your talking about the volume first. :> So, let's find the orange one first cuz yes.

The rectangular prism has the volume of 8.5 x 5.7 x 4.3 and I think you should just use a calculator but I'll just tell you that the volume of this one is 208.335

Now we need to find the volume of the triangular prism which has side lengths of 3.5 6.4 and 5.8 . Now we must remember the strategy for finding the volume of a triangular prism is different because the formula is
V =(1/2)× b × h × l so lets plug in our values. Well, first 3.5 x 6.4 x 5.8 is 129.92 and then we multiply that by 1/2 and I'll tell you that it's 64.96

Finally, let us add the two values to find the total area. 208.335 + 64.96 is... 273.295 now remember the units it meters cubed!

Area for a kite I don’t know how to find the area pls help

dusya [7]

Answer:

63.966

Step-by-step explanation:

Area of a kite is

$\frac{pq}{2}$

where p and q are the diagonals.

The horinzontial diagonal is 8.

We need to find the vertical diagonal length.

The top triangle diagonal measure is

${4}^{2} + {x}^{2} = {7}^{2}$

$16 + {x}^{2} = 49$

${x}^{2} = 33$

$x = \sqrt{33}$

The bottom triangle diagonal measure is

${4}^{2} + {x}^{2} = {11}^{2}$

$1 6 + {x}^{2} = 121$

${x}^{2} = 105$

$x = \sqrt{105}$

Add the two diagonals.

$\sqrt{105} + \sqrt{33}$

Substitute this in for the formula

$\frac{8 \times ( \sqrt{105} + \sqrt{33} }{2}$

Which simplified gu

Ives us

$63.966$

A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish

Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

$1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours$

Time taken by labor to finish and stain each skateboard is given by

$2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours$

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

$a\times (b+c)=a\times b+a\times c$

$36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85$

Hence, the total cost will be $156.85.

What is the total surface area of the figure shown?

4vir4ik [10]

Given:

Composite figure.

The figure splitted into two shapes.

One is vertical cuboid and other is horizontal cuboid

To find:

Total surface area of the figure

Solution:

Vertical cuboid:

Length = 14 inches

Width = 12 inches

Height = 24 inches

Surface area = 2(lw + wh + lh)

= 2(14 × 12 + 12 × 24 + 14 × 24)

= 2(168 + 288 + 336)

Surface area = 1584 square inches

Horizontal cuboid:

Length = 14 inches

Width = 10 inches

Height = 30 - 12 = 18 inches

Surface area = 2(lw + wh + lh)

= 2(14 × 10 + 10 × 18 + 14 × 18)

= 2(140 + 180 + 252)

Surface area = 1144 square inches

Total surface area = 1584 + 1144

= 2728 square inches

The total surface area of the figure is 2728 square inches.
