Answer:
surface are: 300 cm2
volume: 450cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Surface area of a box = 2wl + 2hw + 2 lh
Where w is the width of the box, l is the length of the box, and h is the height of the box.
The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.
S = wl + 2hw + 2 lh
Replacing with the values given:
S = (15x10)+ 2(3x10)+ 2(15x3)
S = 150+60+90=300 cm2
For the volume we simply apply:
Volume of a rectangular prism: length x width x height
V = 15x10x3 = 450cm3
Feel free to ask for more if needed or if you did not understand something.

Vas happenin!!!
So you plug in the 3 into the equation 12-3(3)/2 + 3 [2(3)-4/3
You multiply the parentheses first
3 times 3 is 9
2 times 3 is 6
Then you plug it in again 12-9 / 2 plus 6-4/3
12-9 is 2/2 which is 1
1 plus 6-4/3
6-4 is 2
2/3 is you can stay it as a fraction or the decimal form is 1.5
1 plus 1.5 is 2.5
So your answer in decimal form is 2.5
Fraction form is 2 1/2
Hope this helps *smiles*
