Answer:

440cm³

Step-by-step explanation:

Area of trapezium base=

$\frac{1}{2} \times (a + b) \times h$

$\frac{1}{2} \times (8 + 14) \times 4$

$\frac{1}{2} \times 22 \times 4 \\ = \frac{88}{2} \\ = 44 {cm}^{3}$

Volume=Area or trapezium x Height between trapezium ends

$= 44 \times 10 \\ = 440 {cm}^{3}$

Explanation:
_______________________________
Find the "like terms"; which are:
_______________________________
"4y" and "2y²"
_______________________________
The remaining term is: "7x".
_____________________________________
The problem is a "multiplication problem" :
___________________________________________
7x * 4y * 2y² ; so start by multiplying the "like terms" :
___________________________________________
4y * 2y² = 8y³
____________________________________________
Then the remaining term is "7x";
so, multiply that by our obtained value: "8y³ " :
_____________________________________________
7x * 8y³ = 56xy³ ; which is our answer:
