Answer:
12
Step-by-step explanation:
the lenght is y, the width is also y since the base is a square and since the height is twice the lenght it will be 2y, knowing that we just find the total surface area in terms of y.
which would be: 2(y·y) + 2(y·2y) + 2(2y·y)=360
this then simplifies to= 10y²=360
= y²=36
= y =6
the height therefore is 2y meaning its 2(6)=12
this problem was rather easy its so sad no one helps out in here totally hate this site wish more people helped
