Answer: 213 meters.

Step-by-step explanation:

A=2(wl+hl+hw) is the formula. l = 6, w = 3.5, h = 9 for this problem.

2([3.5 x 6]+[9 x 6]+[3.5 x 9])

2(21+54+31.5)

2(106.5)

A=213

Sorry if this isn’t a great explanation. Hope this helps.

A student claims that 8^3 x 8^-5 is greater than 1. Explain whether the student is correct or not.

nlexa [21]

Remember:
a^m * a^n=a^(m+n)
a^-m=1/a^m

8³ x 8⁻⁵=8³⁻⁵=8⁻²=1/8²=1/64<1

Answer: the student is not correct, because 1/64<1, and 8³ x 8⁻⁵=1/64.
