What you can do is multiply 400*20= 8,000. From here, we know that 399*20 is just one less group of 20 than 400. Therefore, we can subtract (1*20) from 8,000 to get the final answer.
8000-20=7980
Hope this helps!
Answer:
49 cm²
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the length of the side, thus
s³ = 343 ( take the cube root of both sides )
s = ![\sqrt[3]{343}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B343%7D)
= 7, thus
area of base = s² = 7² = 49 cm²
