Answer:
65.4 cm²
Step-by-step explanation:
The volume of a cuboid is calculated by multiplying the length, base, and height together. Since a cube has equal sides, the formula for the volume of a cuboid can be simplified as shown below.
Volume of cube
= side ×side ×side
= side³
Given that the volume is 36 cm³, let's find the length of each side.
side³= 36
Cube root both sides:
side=![\sqrt[3]{36}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B36%7D)
Total surface area of a cube is the sum of the surface areas of its 6 identical square faces.
Area of a square
= side ×side
= side²
Surface area of 1 face= ![(\sqrt[3]{36})^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B36%7D%29%5E2)
Total surface area
= ![6(\sqrt[3]{36} )^2](https://tex.z-dn.net/?f=6%28%5Csqrt%5B3%5D%7B36%7D%20%29%5E2)
= 65.416 (5 s.f.)
= 65.4 cm² (nearest tenth)

Answer:
Hi there !
- A. 1/8 of the original volume
- 24 is the mode
<h2>
Step-by-step explanation:</h2>
<h3>Question 1 :-</h3>
LET RADIUS OF SPHERE= R
VOLUME OF SPHERE= 
WHEN RADIUS IS HALVED RADIUS IF SPHERE=R/2
VOLUME= 
= {(4/3)πR^3}/8
THE VOLUME WILL BECOME 1/8 TH OF THE ORIGINAL VOLUME.
<h2>
Question 2 :-</h2>
Wehave,
Mode+2×Mean=3×Median
⇒Mode=3×Median−2×Mean
Given : Mean=21 and Median=22
Putting the given values, we get
Mode=3×22−2×21=66−42=24.
Hope it helps u....
Stay safe, stay healthy and blessed
Have a great day !
Thank you

Answer: 21n + 70= 21n plus 70
Step-by-step explanation:
step by step explanation the n is 21 plus 70 plus then you have to do equals on the sign 21n in the box where it says n add 21 then add 70 and then add a = sign and your done
