Answer:
Surface area - 0.96, Volume - 0.064
Step-by-step explanation:
2/5- 0.40
For surface area, the equation is 6a^2
When you fill in the variable its
6(0.4)^2
follow pemdas, so you do the exponents first
(0.4)(0.4)
0.16
6(0.16)
0.96
The formula for volume is a^3
0.4^3
(0.4)(0.4)(0.4)
(0.16)(0.4)
0.064
