Answer:
Faces: 7, Edges: 12, Vertices: 7
Step-by-step explanation:
Just count them
82, 84, and 86 are your three consecutive even integers.
If the diameter is 24, the radius must be 12
√(3x²) = 12
<span>3x² = 144 </span>
<span>x² = 48 </span>
<span>. . . . ._ </span>
<span>x = 4√3
</span>Each edge of the cube is twice that or <span>8√ 3
</span>
Hope this helps
Answer:
320 in.²
Step-by-step explanation:
Let's think of the shape as a normal rectangle with a height of 16 inches. Now all we need is the length. If you look at the right corner, it looks like a piece has been cut out. Since that piece has the same length and height of 8 inches, it is a square. This tells us the missing length of the entire length of the rectangle. Now the length of the rectangle is 16 inches + 8 inches, which is 24 inches.
The total area of the rectangle is 16 × 24, which is 384.
Then from the total area, we just need to subtract the area of the cut-out part. The area of the cut-out square is 8 × 8, which is 64.
384 - 64 = 320
The total surface area of the following complex shape is 320 in.²
