Answer:
C. 
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 = 



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 = 
23 can round to 20 and 21 can also round to 20 so all u do is 20x20=400 so 400 is your estimated answer
Answer:
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
