To check whether the statements are correct, we need to convert cm to mm.
surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a
1 cm = 10 mm
7 cm = 70 mm
Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²
<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>
The total will be 57.23. Because tax would be 4.24 and add it to 52.99 and you get 57.23.
Vsphere=(4/3)pi times r^3
r=radius
given that r=2
v=(4/3)pi2^3
v=(4/3)pi8
v=32/3pi cubic inches
about 10.66666pi cubic inches or hmm, roughly 31 cubic inches (guestimated in head)
Answer:
20/10 + 50=52
