Answer:

<u>1,216 cm³</u>

Step-by-step explanation:

Volume (composite space figure) = Volume (pyramid) + volume (prism)

⇒ [16 x 6 x 14 / 3] + [16 x 6 x 8]
⇒ 96 [14/3 + 8]
⇒ 96 [14/3 + 24/3]
⇒ 96 x 38/3
⇒ 32 x 38
⇒ <u>1,216 cm³</u>

2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.

sasho [114]

Step-by-step explanation:

<h2>Answer:-</h2>

$\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}$

Now, let's Solve!

So, according to Question,

Bill = 2x

Tim = 3x-3

Total Candies = 177.

$\bf{x+2x+3x-3=177}$

Totalling x,

$\bf{6x-3=177}$

$\bf{6x=177+3}$

$\bf{6x = 180}$

$\boxed{\sf{x = 30}}$

So, Fred has 30 candies.

Bill's Candies = 2×30 = 60 Candies

Tim's Candies = 3×30-3 = 90-3 = 87 Candies.

Hope it helps :)
