Jandrenn's Surface Area

1)
T =L x W 5 x 10 = 50
F =L x W 10 x 6 = 60
S =L x W 6 x 5 = 30
-----------------------
TOTAL = 140

TSA= 2 (T+F+S)
= 2(50+60+30)
= 2 x 140
= 280 m2

3)


Volume
1)
v=7.5 x 8.5=63.75 m3

2)

V=L x W x H
V=16 x 8 x 20
V= 2560 cm3



3)

V=16 x 6.5 =104 cm3

104 ÷ 8 = 13
13 x 3 =39 cm3



4)
Remove formatting from selection
v=π.r.r.h
v=3.14 x 6 x 6 x 15
v=1695.6 cm3
