You need to find the surface area of the rectangular prism and the triangular prism and add them up to find the answer.
Rectangular prism:
SA=2(lw+wh+lh)
SA=2(437.5+406.25+1137.5)
SA=2(1981.25)
SA=3962.5 sq cm
Triangular prism:
SA=2(1/2bh)+3(slanted height)*w
SA=2(235.75)+3(293.75)
SA=471.5+881.75
SA=1352.75 sq cm
3962.5+1352.75=5315.25 sq cm
Answer:
the value for the expression for below is (4^2) ^1/4 is 2
Answer:
sum of ratio =3+2=5
David'share=£9900x3/5=£5940
Sum of ratio for part= 4+4+2=10
for himself=£5940x4/10=£2376
for wife=£5940x4/10=£2376
for son=£5940x2/10=£1188
his wife gets over son
£2376-£1188=£1188
