Answer 7

:) its a prism :

surface area = 2B + Ph

Answer 8

B = Base area
P = Base perimeter
h = height

Answer 9

find the values and plugin

Answer 10

Notice that Base shape is a triangle of b = 4, h = 3 :

Area of Base = 1/2 * 4 * 3 = ?

Answer 11

sorry I was dealing with something ok and I think it is 4?

Answer 12

Area of Base = 1/2 * 4 * 3 = 1/2 * 12 = 6

Answer 13

^^

Answer 14

oh ok

Answer 15

what about Perimeter of base ?

Answer 16

the Base has sides : 3, 4, 5
so Perimeter = 3 + 4 + 5 = 12

Answer 17

surface area = 2B + Ph
= 2*6 + 12*7

Answer 18

96?

Answer 19

yes !

Answer 20

For the first one?

Answer 21

yes

Answer 22

for second one use below formula :
