Question

Can you please help me with this question ?​

Answer 1

its a prism

Explanation:

to find area of all the sides, you multiply the bottom and top measurements.

12 x 7 is 84cm
`^(2)`

12 x 9 is 108
`cm^(2)`

9 x 7 is 63
`cm^(2)`

for surface area, add the area of all the faces

63x2+108x2+84X2=510

volume is length x width x hight

12 x 9 x 7 = 756
`cm^(3)`

Answer 2

It is a Cuboid

Area of the base = 12x9

Area of the top = 12x9

Area of the right lateral faces = 9x7

Area of the left lateral faces = 9x7

Area of the front face = 12x7

Area of the rear face = 12x7

Total surface area is the sum of above (please do it yourself)

The volume = base surface Area x height

= 12x9x7 = 756

Be reminded to put in the right unit for Area and volumn
