Step 1: Calculate the Volume of the cuboid. The dimensions are: Length ($l$) = 22 cm Breadth ($b$) = 12 cm Height ($h$) = 7.5 cm The formula for the volume of a cuboid is $V = l \times b \times h$. $$V = 22 \text{ cm} \times 12 \text{ cm} \times 7.5 \text{ cm}$$ $$V = 264 \text{ cm}^2 \times 7.5 \text{ cm}$$ $$V = 1980 \text{ cm}^3$$ Step 2: Calculate the Lateral Surface Area (LSA) of the cuboid. The formula for the lateral surface area of a cuboid is $\text{LSA} = 2h(l+b)$. $$\text{LSA} = 2 \times 7.5 \text{ cm} \times (22 \text{ cm} + 12 \text{ cm})$$ $$\text{LSA} = 15 \text{ cm} \times (34 \text{ cm})$$ $$\text{LSA} = 510 \text{ cm}^2$$ Step 3: Calculate the Total Surface Area (TSA) of the cuboid. The formula for the total surface area of a cuboid is $\text{TSA} = 2(lb + bh + hl)$. $$\text{TSA} = 2((22 \text{ cm} \times 12 \text{ cm}) + (12 \text{ cm} \times 7.5 \text{ cm}) + (7.5 \text{ cm} \times 22 \text{ cm}))$$ $$\text{TSA} = 2(264 \text{ cm}^2 + 90 \text{ cm}^2 + 165 \text{ cm}^2)$$ $$\text{TSA} = 2(519 \text{ cm}^2)$$ $$\text{TSA} = 1038 \text{ cm}^2$$ The volume, lateral surface area, and total surface area for the given dimensions are: Volume: $\boxed{\text{1980 cm}^3}$ Lateral Surface Area: $\boxed{\text{510 cm}^2}$ Total Surface Area: $\boxed{\text{1038 cm}^2}$

Step 1: Calculate the Volume of the cuboid. The dimensions are: Length (lll) = 22 cm Breadth (bbb) = 12 cm Height (hhh) = 7.5 cm

The formula for the volume of a cuboid is V=l×b×hV = l \times b \times hV=l×b×h. V=22cm×12cm×7.5 cmV = 22 cm \times 12 cm \times 7.5 \text{ cm}V=22cm×12cm×7.5 cm V=264cm2×7.5 cmV = 264 cm^2 \times 7.5 \text{ cm}V=264cm2×7.5 cm V=1980cm3V = 1980 cm^3V=1980cm3

Step 2: Calculate the Lateral Surface Area (LSA) of the cuboid. The formula for the lateral surface area of a cuboid is LSA=2h(l+b)\text{LSA} = 2h(l+b)LSA=2h(l+b). LSA=2×7.5cm×(22cm+12cm)\text{LSA} = 2 \times 7.5 cm \times (22 cm + 12 cm)LSA=2×7.5cm×(22cm+12cm) LSA=15cm×(34cm)\text{LSA} = 15 cm \times (34 cm)LSA=15cm×(34cm) LSA=510cm2\text{LSA} = 510 cm^2LSA=510cm2

Step 3: Calculate the Total Surface Area (TSA) of the cuboid. The formula for the total surface area of a cuboid is TSA=2(lb+bh+hl)\text{TSA} = 2(lb + bh + hl)TSA=2(lb+bh+hl). TSA=2((22cm×12cm)+(12cm×7.5cm)+(7.5cm×22cm))\text{TSA} = 2((22 cm \times 12 cm) + (12 cm \times 7.5 cm) + (7.5 cm \times 22 cm))TSA=2((22cm×12cm)+(12cm×7.5cm)+(7.5cm×22cm)) TSA=2(264cm2+90cm2+165cm2)\text{TSA} = 2(264 cm^2 + 90 cm^2 + 165 cm^2)TSA=2(264cm2+90cm2+165cm2) TSA=2(519cm2)\text{TSA} = 2(519 cm^2)TSA=2(519cm2) TSA=1038cm2\text{TSA} = 1038 cm^2TSA=1038cm2

The volume, lateral surface area, and total surface area for the given dimensions are: Volume: 1980cm3\boxed{1980 cm^3}1980cm3​ Lateral Surface Area: 510cm2\boxed{510 cm^2}510cm2​ Total Surface Area: 1038cm2\boxed{1038 cm^2}1038cm2​
