Hello from MrBillDoesMath!
Answer:
152 in^2
Discussion:
Surface area =
2 (area of side triangle + area of rectangle face) +
area of bottom rectangle
= 2 ( (1/2) 6*4 + 5*8 ) + 8*6
= 2 ( (1/2) 24 + 40 ) + 48
= 2 (12 +40 ) + 48
= 2(52) + 48
= 104 + 48
= 152
Thank you,

Answer:
378
Step-by-step explanation:
It will also be a multiple of 21 .
As it is divisible by 3 the first possibility is 366 so:-
364 + n = 21m
where n = 2,5,8,11,14...
Trying each number in turn we get:-
364 + 14 = 21m
21m = 378
m = 18
so the answer is 378
One is a fraction the other is a whole number
Maybe try -2/5? I don’t really know-
