Answer 1

Answer:

6.

volume=l×b×h=11×3×4=132in³

surface area =2(lb+bh+lh)=2(11×3+3×4+11×4)=178in²

7.

lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²

curved surface area=2[area oftraingle]=2×1/2×4×3

=12cm²

now

total surface area=72cm²+12cm²=84cm²

8.

volume of traingular prism=area of traingle ×length

=1/2×12×3.4×4=81.6in³

Answer 2

Answer:

6.volume=

$4 \times 3 \times 11 = 132$

surface area

$2(4 \times 3 + 11 \times 3 + 4 \times 11) = 172in$
