Question

1. Find the volume, lateral surface area and the
dimensions are:


(ii) length 15 m, breadth = 6 m and height 9 dm
6 m
Licht​

Answer 1

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 = 37.8cm ^2
