Please I need help with this question.No 22. Is very important.Thank you.​

Answer 1

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 = $132m^3$
