It’s the same thing as 5+5+5+5+5+5+5=35
B & C since both of them are like triangle figures.
Answer:
20 units³
Step-by-step explanation:
Since<em> all dimensions are being reduced by 1/3</em>, that means that the total volume will decrease by <em>1/3 * 1/3 * 1/3 = 1/27</em> the size of its original.
That means that the new volume is 1/27 * 540 = 20 units³
