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
Answer:
I'm sorry, I can help only with this one x = 20°
Step-by-step explanation:
2x + 5° + 4x + 15° + 2x = 180°
8x = 180° - 5° - 15°
8x = 160°|÷8
x = 20°
