Answer:
Option 1
Step-by-step explanation:
the formula for finding the volume of a pyramid is lwh/3. in this case the length or l is 6, the width or w is 4 and the height or h is 8, multiply all of those and then multiply the product of that by 1/3 or divide lwh by 3, either way youll get the same thing. the 10 inches is useless for finding the volume btw
Please mark as brainliest :)
since we are dealing with composite figures, we need to find the anwser to each shape.
<h3>Rectangle</h3>
A = 16 x 6 = 96
<h3>Square</h3>
Since we do not have an exact length, we have to find the <em>difference (subtraction). </em>14, bottom length of composite figure, minus 6 (length of rectangle) equals 8.
Now, you can use this process for the width. 16, width of shape, 2 half-width of rectangle, equals 14.
A = 8 x 14 = 112
So, 112 + 96 = 208 is your anwser
Answer:
3f+6
Step-by-step explanation:
To solve this, we combine like terms which are in this case 4f and f. 4f-9-f+15 is (4f-f)+(-9+15), which we simplify to 3f+6.
Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches
