(it says 8.5 at the left edge of orange) Find the total area of the prisms
tiny-mole [99]

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!

the sides of a triangle, in centimetres,are x,2x-3 and 2x+5. The perimeter of the triangle is 57 cm.a)write down an equation for
soldier1979 [14.2K]

Answer:

11 cm, 19 cm, 27 cm

Step-by-step explanation:

Triangles have 3 sides and perimeter is the sum of all side lengths. So the equation is x + (2x-3) + (2x+5) = 57.

x + (2x-3) + (2x+5) = 57

x + 2x - 3 + 2x + 5 = 57

x + 2x + 2x - 3 + 5 = 57

5x + 2 = 57

5x = 57 -2

5x = 55

x = 11

Now that we know the value of x, we can figure out the side lengths. The first side (x) is 11 cm long, the second side (2x - 3) is 19 cm, and the third side (2x + 5) is 27 cm long.

Find the area of the figure.
jasenka [17]
Divide into shapes that you can find the area of.....

you also have to cross out the 5 and the 4s because you will not need them

2×2= 4 sq. cm
2×2= 4 sq. cm
9×2 = 18 sq. cm

18 + 4 + 4 = 26 sq. cm

so the area is 26 sq. cm
