I would say 19.
If you take out the 6s and just look at the rest you have 4, 9, 14.
It is adding 5 each time and just have a 6 between each one.
So logically I would say 19.

Usimov [2.4K]

He needs 13 cans of paint.

The lateral area is given by the area of 5 rectangles, whose dimensions are 15 by 5:
5(15)(5) = 375

Divide this by 30:
375/30 = 12.5 ≈ 13

Can someone help me pls

FrozenT [24]

There are 4 lateral faces that are triangles. Each triangle is: A = $\frac{b x h}{2}$
A = $\frac{16 x 22}{2}$
   = 176

There is one base that is a square. A = L x W
A = 16 x 16
   = 256

Surface area = 256 + 4(176)
                     = 256 + 704
                     = 960
