Question

total surface area of a cuboid with length 15m breadth 6 m height 0.9m​

Answer 1

Answer:

pls mark me as brainliest

Step-by-step explanation:

Given Length=15m, breadth=6m and height=9m We know that volume of cuboid= length × breadth × height V = (15 × 6 × 0.9) V = 81m3 We know that total surface area of cuboid= 2(l b + b h + h l) Surface area = 2 (15 × 6 + 6 × .9 + .9 × 15) Surface area = 2 (90 + 13.5 + 5.4) Total Surface area = 217.8m2 We know that lateral surface area of cuboid= 2 [(l + b) × h] Lateral surface area = 2 [(15 + 6) × 0.9] Lateral surface area = 37.8 m2

Answer 2

Answer:

length ( l )=15m

breadth ( b )=6m

height (h)=9dm=(9/10)m=0.9m

therefore, volume= l×b×h

=15×6×0.9

=81m^3
