Which expression represents the volume, in cubic

muminat

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

$V_1=length\times breadth\times height$

$V_1=(8)(6)(4)$

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

$V_2=\dfrac{1}{3}\times length\times breadth\times height$

$V_2=(\dfrac{1}{3})(8)(6)(6)$

The volume of composite figure is

$V=V_1+V_2$

$V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)$

It can be written as

$V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)$

Therefore, the correct option is A.

The length of a rectangle is three times its width. if the area of the rectangle is 300 yd2 , find its perimeter.

Svetradugi [14.3K]

Let, width = x
Length = 3x

It is given that, 3x * x = 300
3x² = 300
x² = 300 / 3
x = √100
x = 10
& 3x = 3(10) = 30

Perimeter = 2(l + w)
P = 2(10 + 30)
P = 2(40) = 80

In short, Your Answer would be 80 Yards

Hope this helps!
