Which expression represents the volume, in cubic units, of the composite figure? One-third(8)(6)(6) (8)(6)(4) One-third(8)(6)(10
vaieri [72.5K]

The expression of Volume in cubic meter  \frac{1}{3} (8)(6)(6)+(8)(6)(4)

The correct option is (1)

<h3>What is Volume?</h3>

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

 

Volume of rectangular pyramid= \frac{1}{3} * base area* height

                                                   = \frac{1}{3} * 6*8*(10-4)

                                                   =\frac{1}{3} * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =\frac{1}{3} * 6*8*6 + 4*6*8

                     = \frac{1}{3} (8)(6)(6)+(8)(6)(4)

So, The expression of Volume in cubic meter  \frac{1}{3} (8)(6)(6)+(8)(6)(4).

HELP IM USING ALL MY POINTS
Romashka-Z-Leto [24]

Answer:

5 days

Step-by-step explanation:

If you write it out it will look like this 8 1/2÷1 7/10

since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2    1 7/10 -> 17/10

So it looks like 17/2÷17/10

because of maths you have to turn 17/10 into 10/17

And when you do the maths (multiply it together) you get 5
