Answer:
1.76
Step-by-step explanation:
The formula is l x w x h
2 x 2.2 x 0.2 = 0.88
The prisms are the same so
0.88 + 0.88 = 1.76

Answer:
x = 27
Step-by-step explanation:
ΔBRD and ΔQCD are similar, hence the ratios of corresponding sides are equal, that is
= 
note that BD = 26 + 39 = 65
substitute values into the ratio equation
=
( cross- multiply )
65x = 39(x + 18)
65x = 39x + 702 ( subtract 39x from both sides )
26x = 702 ( divide both sides by 26 )
x = 27
