Answer:

C. 132m^3

Step-by-step explanation:

Height = 4

Length = 6

Breadth = 7

Note : We were asked to find volume of the cuboid

Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.

 Step 1

Find the area of the trapezium

Area of a trapezium = \frac{1}{2} (a+b)h

\frac{1}{2} (4+7)*4

\frac{1}{2} (11)4\\

\frac{1}{2} *44\\= 22

 Step 2

Calculate the volume of the cuboid

Volume of a cuboid =length× breadth × height

In this case , the volume will be our length ×  Area of a trapezium

 V= 6 × 22

V = 132m^3

No it is not.

Step-by-step explanation:

Reason.

For geometric: common ratio r should be equal

r = T2/T1 = T3/T2 but is not true here as -6/-14 is not equal to 2/-6
